MPOP(1) General Commands Manual MPOP(1) NAME mpop - A POP3 client SYNOPSIS Mail retrieval mode (default): mpop [option...] [--] [account...] mpop --host=host [option...] Configuration mode: mpop --configure <mailaddress> Server information mode: mpop [option...] --serverinfo [account...] mpop --host=host [option...] --serverinfo DESCRIPTION In mail retrieval mode of operation, mpop retrieves mails from one or more POP3 mailboxes, optionally does some filtering, and delivers them through a mail delivery agent (MDA), to a maildir folder, or to an mbox file. Mails that were successfully delivered before will not be retrieved a second time, even if errors occur or mpop is terminated in the middle of a ses- sion. In server information mode, mpop prints information about one or more POP3 servers. If no account names are given on the command line, one named default will be used. The best way to start is probably to have a look at the EXAMPLES section. EXIT STATUS The standard sendmail exit codes are used, as defined in sysexits.h. OPTIONS Options override configuration file settings, for every used account. General Options --version Print version information, including information about the libraries used. --help Print help. -P, --pretend Print the configuration settings that would be used, but do not take further action. An asterisk (`*') will be printed instead of your password. -d, --debug Print lots of debugging information, including the whole con- versation with the server. Be careful with this option: the (potentially dangerous) output will not be sanitized, and your password may get printed in an easily decodable format! This option implies --half-quiet, because the progress output would interfere with the debugging output. Changing the mode of operation --configure=mailaddress Generate a configuration for the given mail address and print it. This can be modified or copied unchanged to the configu- ration file. Note that this only works for mail domains that publish appropriate SRV records; see RFC 8314. -S, --serverinfo Print information about the POP3 server(s) and exit. This in- cludes information about supported features (pipelining, au- thentication methods, TOP command, ...), about parameters (time for which mails will not be deleted, minimum time be- tween logins, ...), and about the TLS certificate (if TLS is active). Configuration options -C, --file=conffile Use the given file instead of ~/.mpoprc or $XDG_CON- FIG_HOME/mpop/config as the user configuration file. --host=hostname Use this server with settings from the command line; do not use any configuration file data. This option disables loading of the configuration file. You cannot use both this option and account names on the command line. --port=number Set the port number to connect to. See the port command. --source-ip=[IP] Set or unset an IP address to bind the socket to. See the source_ip command. --proxy-host=[IP|hostname] Set or unset a SOCKS proxy to use. See the proxy_host com- mand. --proxy-port=[number] Set or unset a port number for the proxy host. See the proxy_port command. --socket=[socketname] Set or unset a local unix domain socket name to connect to. See the socket command. --timeout=(off|seconds) Set a network timeout. See the timeout command. --pipelining=(auto|on|off) Enable or disable POP3 pipelining. See the pipelining com- mand. --received-header[=(on|off)] Enable or disable the Received header. See the re- ceived_header command. --auth[=(on|method)] Set the authentication method to automatic (with "on") or manually choose an authentication method. See the auth com- mand. --user=[username] Set or unset the user name for authentication. See the user command. --passwordeval=[cmd] Evaluate password for authentication. See the passwordeval command. --tls[=(on|off)] Enable or disable TLS/SSL. See the tls command. --tls-starttls[=(on|off)] Enable or disable STARTTLS for TLS. See the tls_starttls com- mand. --tls-trust-file=[file] Set or unset a trust file for TLS. See the tls_trust_file command. --tls-crl-file=[file] Deprecated. Set or unset a certificate revocation list (CRL) file for TLS. See the tls_crl_file command. --tls-fingerprint=[fingerprint] Set or unset the fingerprint of a trusted TLS certificate. See the tls_fingerprint command. --tls-key-file=[file] Set or unset a key file for TLS. See the tls_key_file com- mand. --tls-cert-file=[file] Set or unset a cert file for TLS. See the tls_cert_file com- mand. --tls-certcheck[=(on|off)] Enable or disable server certificate checks for TLS. See the tls_certcheck command. --tls-priorities=[priorities] Set or unset TLS priorities. See the tls_priorities command. --tls-host-override=[host] Set or unset override for TLS host verification. See the tls_host_override command. --tls-min-dh-prime-bits=[bits] Deprecated, use --tls-priorities instead. Set or unset mini- mum bit size of the Diffie-Hellmann (DH) prime. See the tls_min_dh_prime_bits command. Options specific to mail retrieval mode -q, --quiet Do not print status or progress information. -Q, --half-quiet Print status but not progress information. -a, --all-accounts Query all accounts in the configuration file. -A, --auth-only Authenticate only; do not retrieve mail. Useful for SMTP-af- ter-POP. -s, --status-only Print number and size of mails in each account only; do not retrieve mail. -n, --only-new[=(on|off)] Process only new messages. See the only_new command. -k, --keep[=(on|off)] Do not delete mails from POP3 servers, regardless of other options or settings. See the keep command. --killsize=(off|size) Set or unset kill size. See the killsize command. --skipsize=(off|size) Set or unset skip size. See the skipsize command. --filter=[program] Set a filter which will decide whether to retrieve, skip, or delete each mail by investigating the mail's headers. See the filter command. --delivery=method,method_arguments... How to deliver messages received from this account. See the delivery command. Note that a comma is used instead of a blank to separate the method from its arguments. --uidls-file=filename File to store UIDLs in. See the uidls_file command. USAGE A suggestion for a suitable configuration file can be generated using the --configure option. The default configuration file is ~/.mpoprc or $XDG_CONFIG_HOME/mpop/config. Settings in this file can be changed by com- mand line options. A configuration file is a simple text file. Empty lines and comment lines (first non-blank character is '#') are ignored. Every other line must con- tain a command and may contain an argument to that command. The argument may be enclosed in double quotes ("). If a file name starts with the tilde (~), this tilde will be replaced by $HOME. If a command accepts the argument on, it also accepts an empty argument and treats that as if it was on. Commands are organized in accounts. Each account starts with the account command and defines the settings for one POP3 account. Commands are as follows: defaults Set defaults. The following configuration commands will set default values for all following account definitions. account name [:account[,...]] Start a new account definition with the given name. The current de- fault values are filled in. If a colon and a list of previously defined accounts is given after the account name, the new account, with the filled in default val- ues, will inherit all settings from the accounts in the list. eval cmd Replace the current configuration file line with the first line of the output (stdout) of the command cmd. This can be used to decrypt settings or to create them via scripts. For example, eval echo host localhost replaces the current line with host localhost. Note that every eval line will be evaluated when the configuration file is read. Note that for passwords you can also use the passwordeval command instead of eval password cmd. This has the advantage that the com- mand is only evaluated if needed. host hostname The POP3 server to retrieve mails from. The argument may be a host name or a network address. Every account definition must contain this command. port number The port that the POP3 server listens on. The default is 110 ("pop3"), unless TLS without STARTTLS is used, in which case it is 995 ("pop3s"). source_ip [IP] Set a source IP address to bind the outgoing connection to. Useful only in special cases on multi-home systems. An empty argument dis- ables this. proxy_host [IP|hostname] Use a SOCKS proxy. All network traffic will go through this proxy host, including DNS queries, except for a DNS query that might be necessary to resolve the proxy host name itself (this can be avoided by using an IP address as proxy host name). An empty hostname argu- ment disables proxy usage. The supported SOCKS protocol version is 5. If you want to use this with Tor, see also "Using mpop with Tor" below. proxy_port [number] Set the port number for the proxy host. An empty number argument re- sets this to the default port, which is 1080 ("socks"). socket socketname Set the file name of a unix domain socket to connect to. This over- rides both host/port and proxy_host/proxy_port. timeout (off|seconds) Set or unset a network timeout, in seconds. The default is 180 sec- onds. The argument off means that no timeout will be set, which means that the operating system default will be used. pipelining (auto|on|off) Enable or disable POP3 pipelining. You should never need to change the default setting, which is auto: mpop enables pipelining for POP3 servers that advertise this capability, and disables it for all other servers. Pipelining can speed up a POP3 session substan- tially. auth [(on|method)] Choose an authentication method. The default argument on chooses a method automatically. Usually a user name and a password are used for authentication. The user name is specified in the configuration file with the user com- mand. There are five different methods to specify the password: 1. Add the password to the system key ring. Currently supported key rings are the Gnome key ring and the Mac OS X Keychain. For the Gnome key ring, use the command secret-tool (part of Gnome's libse- cret) to store passwords: secret-tool store --label=mpop host pop.freemail.example service pop3 user joe.smith. On Mac OS X, use the following command: security add-internet-password -s pop.freemail.example -r pop3 -a joe.smith -w. In both examples, re- place pop.freemail.example with the POP3 server name, and joe.smith with your user name. 2. Store the password in an encrypted files, and use passwordeval to specify a command to decrypt that file, e.g. using GnuPG. See EXAM- PLES. 3. Store the password in the configuration file using the password command. (Usually it is not considered a good idea to store pass- words in cleartext files. If you do it anyway, you must make sure that the file can only be read by yourself.) 4. Store the password in ~/.netrc. This method is probably obsolete. 5. Type the password into the terminal when it is required. It is recommended to use method 1 or 2. Multiple authentication methods exist. Most servers support only some of them. The following user / password methods are supported: user (a simple plain text method supported by all servers), plain (another simple cleartext method, supported by almost all servers), scram-sha-1 and scram-sha-1-plus (a method that avoids cleartext passwords and re- quires the server to prove that it is in posession of the (hashed and salted) password, which prevents some man-in-the-middle-attacks. The -plus variant additionally uses TLS channel binding information for even better security guarantees), scram-sha-256 and scram-sha-256-plus (same but with a stronger hash function), apop (an obsolete method that avoids cleartext passwords, but is not con- sidered secure anymore), cram-md5 (an obsolete method that avoids cleartext passwords, but is not considered secure anymore), di- gest-md5 (an overcomplicated obsolete method that avoids cleartext passwords, but is not considered secure anymore), login (a non-stan- dard cleartext method similar to but worse than the plain method), ntlm (an obscure non-standard method that is now considered broken; it sometimes requires a special domain parameter passed via ntlmdo- main). If no method is specified, mpop will autoselect one based on secu- rity benefits. With TLS, the order is scram-sha-256-plus, scram-sha-1-plus, scram-sha-256, scram-sha-1, plain, followed by some of the obsolete methods if nothing else is available. Without TLS, only scram-sha-256 and scram-sha-1 are considered. There are currently three authentication methods that are not based on user / password information and have to be chosen manually: oau- thbearer or its predecessor xoauth2 (an OAuth2 token from the mail provider is used as the password. See the documentation of your mail provider for details on how to get this token. The passwordeval command can be used to pass the regularly changing tokens into mpop from a script or an environment variable), external (the authentica- tion happens outside of the protocol, typically by sending a TLS client certificate, and the method merely confirms that this authen- tication succeeded), and gssapi (the Kerberos framework takes care of secure authentication, only a user name is required). It depends on the underlying authentication library and its version whether a particular method is supported or not. Use --version to find out which methods are supported. user login Set the user name for authentication. An empty argument unsets the user name. password secret Set the password for authentication. An empty argument unsets the password. Consider using the passwordeval command or a key ring in- stead of this command, to avoid storing cleartext passwords in the configuration file. passwordeval [cmd] Set the password for authentication to the output (stdout) of the command cmd. This can be used e.g. to decrypt password files on the fly or to query key rings, and thus to avoid storing cleartext pass- words. ntlmdomain [domain] Set a domain for the ntlm authentication method. This is obsolete. tls [(on|off)] Enable or disable TLS (also known as SSL) for secured connections. Transport Layer Security (TLS) "... provides communications privacy over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery" (quote from RFC2246). A server can use TLS in one of two modes: via a STARTTLS command (the session starts with the normal protocol initialization, and TLS is then started using the protocol's STARTTLS command), or immedi- ately (TLS is initialized before the normal protocol initialization; this requires a separate port). The first mode is the default, but you can switch to the second mode by disabling tls_starttls. When TLS is started, the server sends a certificate to identify it- self. To verify the server identity, a client program is expected to check that the certificate is formally correct and that it was is- sued by a Certificate Authority (CA) that the user trusts. (There can also be certificate chains with intermediate CAs.) The list of trusted CAs is specified using the tls_trust_file com- mand. The default value ist "system" and chooses the system-wide default, but you can also choose the trusted CAs yourself. A fundamental problem with this is that you need to trust CAs. Like any other organization, a CA can be incompetent, malicious, sub- verted by bad people, or forced by government agencies to compromise end users without telling them. All of these things happened and continue to happen worldwide. The idea to have central organiza- tions that have to be trusted for your communication to be secure is fundamentally broken. Instead of putting trust in a CA, you can choose to trust only a single certificate for the server you want to connect to. For that purpose, specify the certificate fingerprint with tls_fingerprint. This makes sure that no man-in-the-middle can fake the identity of the server by presenting you a fraudulent certificate issued by some CA that happens to be in your trust list. However, you have to up- date the fingerprint whenever the server certificate changes, and you have to make sure that the change is legitimate each time, e.g. when the old certificate expired. This is inconvenient, but it's the price to pay. Information about a server certificate can be obtained with --serverinfo --tls --tls-certcheck=off. This includes the issuer CA of the certificate (so you can trust that CA via tls_trust_file), and the fingerprint of the certificate (so you can trust that par- ticular certificate via tls_fingerprint). TLS also allows the server to verify the identity of the client. For this purpose, the client has to present a certificate issued by a CA that the server trusts. To present that certificate, the client also needs the matching key file. You can set the certificate and key files using tls_cert_file and tls_key_file. This mechanism can also be used to authenticate users, so that traditional user / password authentication is not necessary anymore. See the external mechanism in auth. You can also use client certificates stored on some external authen- tication device by specifying GnuTLS device URIs in tls_cert_file and tls_key_file. You can find the correct URIs using p11tool --list-privkeys --login (p11tool is bundled with GnuTLS). If your device requires a PIN to access the data, you can specify that using one of the password mechanisms (e.g. passwordeval, password). tls_starttls [(on|off)] Choose the TLS variant: start TLS from within the session (on, de- fault), or tunnel the session through TLS (off). tls_trust_file file Activate server certificate verification using a list of trusted Certification Authorities (CAs). The default is the special value "system", which selects the system default. An empty argument dis- ables trust in CAs. If you select a file, it must be in PEM format, and you should also use tls_crl_file. tls_crl_file [file] This sets a certificate revocation list (CRL) file for TLS, to check for revoked certificates (an empty argument, which is the default, disables this). OCSP is an alternative to CRL files. When GnuTLS is used, stapled OCSP information will be checked automatically, and the MustStaple TLS extension is supported, however no manual OCSP queries will be sent when stapled OCSP information is missing. With other TLS li- braries, behavior may be different. tls_fingerprint [fingerprint] Set the fingerprint of a single certificate to accept for TLS. This certificate will be trusted regardless of its contents (this over- rides tls_trust_file). The fingerprint should be of type SHA256, but can for backwards compatibility also be of type SHA1 or MD5 (please avoid this). The format should be 01:23:45:67:.... Use --serverinfo --tls --tls-certcheck=off --tls-fingerprint= to get the server certificate fingerprint. tls_key_file file Send a client certificate to the server (use this together with tls_cert_file}). The file must contain the private key of a cer- tificate in PEM format. An empty argument disables this feature. tls_cert_file file Send a client certificate to the server (use this together with tls_key_file). The file must contain a certificate in PEM format. An empty argument disables this feature. tls_certcheck [(on|off)] Enable or disable checks of the server certificate. They are enabled by default. Disabling them will override tls_trust_file and tls_fingerprint. WARNING: When the checks are disabled, TLS ses- sions will not be secure! tls_priorities [priorities] Set priorities for TLS session parameters. The default is set by the TLS library and can be selected by using an empty argument to this command. The interpretation of the priorities string depends on the TLS library. Use --version to find out which TLS library you use. For GnuTLS, see the section on Priority Strings in the manual. For libtls, the priorites string is a space-separated list of para- meter strings prefixed with either PROTOCOLS=, CIPHERS=, or ECDHE- CURVES=. These parameter strings will be passed to the functions tls_config_parse_protocols, tls_config_set_ciphers, and tls_con- fig_set_ecdhecurves. Unrecognized parts of the priorities string will be ignored. Example: "PROTOCOLS=TLSv1.3 CIPHERS=ECDHE-RSA- AES128-SHA256 ECDHECURVES=P-384". tls_host_override [host] By default, TLS host verification uses the host name given by the host command. This command allows one to use a different host name for verification. This is only useful in special cases. tls_min_dh_prime_bits [bits] Deprecated, use tls_priorities instead. Set or unset the minimum number of Diffie-Hellman (DH) prime bits accepted for TLS sessions. The default is set by the TLS library and can be selected by using an empty argument to this command. Only lower the default (for exam- ple to 512 bits) if there is no other way to make TLS work with the remote server. delivery method method_arguments... How to deliver messages received from this account. delivery mda command Deliver the mails through a mail delivery agent (MDA). All occurrences of %F in the command will be replaced with the envelope from address of the current message (or MAILER-DAEMON if none is found). Note that this address is guaranteed to contain only letters a-z and A-Z, digits 0-9, and any of ".@_-+/", even though that is only a subset of what is theoretically allowed in a mail address. Other char- acters, including those interpreted by the shell, are re- placed with "_". Nevertheless, you should put %F into single quotes: '%F'. Use "delivery mda /usr/bin/procmail -f '%F' -d $USER" for the procmail MDA. Use "delivery mda /usr/sbin/sendmail -oi -oem -f '%F' -- $USER" to let your MTA handle the mail. Use "delivery mda /usr/local/bin/msmtp --host=localhost --from='%F' -- $USER@`hostname`.`dnsdomainname`" to pass the mail to your MTA via SMTP. (This is what fetchmail does by default.) delivery maildir directory Deliver the mails to the given maildir directory. The direc- tory must exist and it must have the maildir subdirectories cur, new, and tmp; mpop will not create directories. This de- livery type only works on file systems that support hard links. delivery mbox mbox-file Deliver the mails to the given file in mbox format. The file will be locked with fcntl(2). mpop uses the MBOXRD mbox for- mat variant; see the documentation of the mbox format. delivery exchange directory Deliver the mails to the given Exchange pickup directory. The directory must exist. If the delivery method needs to parse the mail headers for an enve- lope from address (the mda method if the command contains %F, and the mbox method), then it needs to create a temporary file to store the mail headers (but not the body) in. uidls_file filename The file to store UIDLs in. These are needed to identify new mes- sages. %U in the filename will be replaced by the username of the current account. %H in the filename will be replaced by the host- name of the current account. If the filename contains directories that do not exist, mpop will create them. mpop locks this file for exclusive access when accessing the associated POP3 account. The default value is "~/.mpop_uidls/%U_at_%H". You can also use a single UIDLS file for multiple accounts, but then you cannot poll more than one of these accounts at the same time. only_new [(on|off)] By default, mpop processes only new messages (new messages are those that were not already successfully retrieved in an earlier session). If this option is turned off, mpop will process all messages. keep [(on|off)] Keep all mails on the POP3 server, never delete them. The default behaviour is to delete mails that have been successfully retrieved or filtered by kill filters. killsize (off|size) Mails larger than the given size will be deleted (unless the keep command is used, in which case they will just be skipped). The size argument must be zero or greater. If it is followed by a `k' or an `m', the size is measured in kibibytes/mebibytes instead of bytes. Note that some POP3 servers report slightly incorrect sizes for mails; see NOTES below. When killsize is set to 0 and keep is set to on, then all mails are marked as retrieved, but no mail gets deleted from the server. This can be used to synchronize the UID list on the client to the UID list on the server. skipsize (off|size) Mails larger than the given size will be skipped (not downloaded). The size argument must be zero or greater. If it is followed by a `k' or an `m', the size is measured in kibibytes/mebibytes instead of bytes. Note that some POP3 servers report slightly incorrect sizes for mails; see NOTES below. filter [command] Set a filter which will decide whether to retrieve, skip, or delete each mail by investigating the mail's headers. The POP3 server must support the POP3 TOP command for this to work; see option --server- info above. An empty argument disables filtering. All occurrences of %F in the command will be replaced with the enve- lope from address of the current message (or MAILER-DAEMON if none is found). Note that this address is guaranteed to contain only letters a-z and A-Z, digits 0-9, and any of ".@_-+/", even though that is only a subset of what is theoretically allowed in a mail ad- dress. Other characters, including those interpreted by the shell, are replaced with "_". Nevertheless, you should put %F into single quotes: '%F'. All occurrences of %S in the command will be replaced with the size of the current mail as reported by the POP3 server. The mail headers (plus the blank line separating the headers from the body) will be piped to the command. Based on the return code, mpop decides what to do with the mail: 0: proceed normally; no special action 1: delete the mail; do not retrieve it 2: skip the mail; do not retrieve it Return codes greater than or equal to 3 mean that an error occurred. The sysexits.h error codes may be used to give information about the kind of the error, but this is not necessary. received_header [(on|off)] Enable or disable adding a Received header. By default, mpop prepends a Received header to the mail during delivery. This is re- quired by the RFCs if the mail is subsequently further delivered e.g. via SMTP. FILTERING There are three filtering commands available. They will be executed in the following order: killsize skipsize filter If a filtering command applies to a mail, the remaining filters will not be executed. EXAMPLES Configuration file # Example for a user configuration file ~/.mpoprc # # This file focusses on TLS, authentication, and the mail delivery method. # Features not used here include mail filtering, timeouts, SOCKS proxies, # TLS parameters, and more. # Set default values for all following accounts. defaults # Always use TLS. tls on # Set a list of trusted CAs for TLS.

This method is proba- bly not # relevant anymore. # Password method 5: Do not specify a password. Mpop will then prompt you for # it. This means you need to be able to type into a terminal when mpop runs. # A second mail box at the same freemail service account freemail2 : freemail user joey # The POP3 server of your ISP account isp host mail.isp.example auth on user 12345 # Your ISP runs SpamAssassin, so test each mail for the "X-Spam-Status: Yes" # header, and delete all mails with this header before downloading them. filter if [ "`grep "^X-Spam-Status: Yes"`" ]; then exit 1; else exit 0; fi # Set a default account account default : freemail Filtering with SpamAssassin The command filter "/path/to/spamc -c > /dev/null" will delete all mails that SpamAssassin thinks are spam. Since no message body is passed to Spa- mAssassin, you should disable all body-specific tests in the SpamAssassin configuration file; for example set use_bayes 0. If your mail provider runs SpamAssassin for you, you just have to check for the result. The following script can do that when used as an mpop filter: #!/bin/sh if [ "`grep "^X-Spam-Status: Yes"`" ]; then exit 1 # kill this message else exit 0 # proceed normally fi Since the filter command is passed to a shell, you can also use this di- rectly: filter if [ "`grep "^X-Spam-Status: Yes"`" ]; then exit 1; else exit 0; fi Using mpop with Tor Use the following settings: proxy_host 127.0.0.1 proxy_port 9050 tls on Use an IP address as proxy host name, so that mpop does not leak a DNS query when resolving it. TLS is required to prevent exit hosts from reading your POP3 session. FILES ~/.mpoprc or $XDG_CONFIG_HOME/mpop/config Default configuration file. ~/.mpop_uidls Default directory to store UIDLs files in. ~/.netrc and SYSCONFDIR/netrc The netrc file contains login information. Before prompting for a password, msmtp will search it in ~/.netrc and SYSCONFDIR/netrc. ENVIRONMENT $USER, $LOGNAME These variables override the user's login name. $LOGNAME is only used if $USER is unset. The user's login name is used for Received headers.
