DBMAIL-USERS(8) DBMAIL-USERS(8) NAME dbmail-users - manages the DBMail user database. SYNOPSIS dbmail-users [MODE] [MODE OPTIONS] dbmail-users --add-user user [options] dbmail-users --change-user user [options] dbmail-users --delete-user user dbmail-users --empty-user-mailboxes user [options] dbmail-users --list-users dbmail-users --list-user user dbmail-users --change-user user --password password --pw-type pwtype dbmail-users --change-user user --add-alias address dbmail-users --change-user user --delete-alias address dbmail-users --forward address --add-forward address dbmail-users --forward address --delete-forward address DESCRIPTION The dbmail-users program enables you to manage the DBMail users. It lets you add, delete and change users as well as show information about a spe- cific user or display a list of existing users. It also has the capability of adding/removing separate aliases. MODE -a, --add-user user Add a user -c, --change-user user Change details for a user -d, --delete-user user Delete a user -e, --empty-user-mailboxes user Empty all mailboxes for a user -L, --list-users List information for all users -l, --list-user userspec List information for matching users -x, --forward alias Create an external forwarding address MODE OPTIONS --enable enable authentication for user --disable disable authentication for user -w --password Specify user's password on the command line. Use with --change-user -W, --pw-file file Read from a file or prompt for a user's password.+ Use with --add-user and --change-user -p, --pw-type type Password type may be one of the following: plaintext, crypt, md5-hash, md5-digest, crypt-raw, md5-hash-raw, md5-digest-raw, md5-base64, md5-base64-raw, whirlpool, sha512, sha256, sha1, tiger. Use with --add-user and --change-user -P, --pw-shadow file Pull encrypted password from the shadow file. Use with --add-user and --change-user -u, --user user New username Use with --change-user to change the username -g, --client cid Assign the user to a client. Use with --add-user and --change-user -m, --max-quota max Set the maximum mail quota in <bytes>B, <kbytes>K, or <mbytes>M, de- fault in bytes If set to 0, there will be no limit. Use with --add-user and --change-user -s, --add-alias alias[,alias...] Adds a list of recipient aliases. An alias is an e-mail address that is being delivered to the DBMail mailsystem and should be delivered to this user. Use with --add-user and --change-user -S, --delete-alias alias[,alias...] Removes a list of recipient aliases. Use wildcards ? and * to match any single character and any number of characters, respectively. Use with --add-user and --change-user -t, --add-forward forward[,forward...] Adds a list of deliver-to forwards. Use with --forward -T, --delete-forward forward[,forward...] Removes a list of deliver-to forwards. Use wildcards ? and * to match any single character and any number of characters, respectively. Use with --forward --security-password specify a separate security fall-back password --security-action select the security action value (default 0) COMMON OPTIONS -f, --config configfile Specify an alternate config file. Use dbmail-<utility> --help to show the default location. -q, --quiet Quietly skip interactive prompts and helpful status messages which would otherwise be printed to stdout. Use two -q's to silence errors which would otherwise be printed to stderr. -v, --verbose Operate verbosely. Some of the utilities in the DBMail suite can take two -v's for extra verbosity. Those which don't understand this conven- tion won't complain about having the extra -v and will simply operate at their normal verbosity. -V, --version Show the version and copyright, then exit. -h, --help Show a brief summary of options, then exit. ALIASES AND FORWARDS What are aliases and forwards and what is the difference between them? Users are known to the outside world by their email address, to avoid con- fusion DBMail uses aliases for incoming email addresses and forwards for outgoing addresses where a user has moved to another organisation and their email is forwarded on to their new address. DBMail users receive email using one or more alias addresses. When a user moves to another organisation or domain, they can have their email forwarded onwards. ALIASES When creating a new user account, you should add an initial alias that de- livers to the account name, or make the account in the form of a fully qualified email address. For example, the user named Baz created like this: dbmail-users --add-user baz --pw-type crypt --password secret After creating the account you add an alias: dbmail-users --change-user baz --add-alias baz@example.com You may add multiple aliases by repeatedly calling dbmail-users, or by calling it with a comma-separated list of aliases: dbmail-users --change-user baz --add-alias baz@example.com,baz@example.org Three catch-all modes are also supported, for domains, sub-domains, and lo- cal parts: dbmail-users --add-user baz --add-aliass @example.com dbmail-users --add-user baz --add-alias @.allsubs.example.com dbmail-users --add-user baz --add-alias baz@ The first example catches email addressed to any user @example.com and de- livers it to Baz's INBOX. The second example catch email address to any user at any subdomain below .allsubs.example.com (not including allsubs.ex- ample.com itself!) The third example catches email addressed to baz@ at any domain. There is no support for delivering to a particular mailbox other than INBOX via the aliases system. Please use a Sieve script to sort mail like this. FORWARDS Incoming messages addressed to particular email addresses can be forwarded to an outside email addresses, piped out to a command (when prepended with | pipe) or piped out with an mbox-style From line to a command (when prepended with ! bang). For example: dbmail-users --forward bar@example.com --add-alias bar@another.example.net dbmail-users --forward bar@example.com --add-alias "|/usr/sbin/superspamtrapper" dbmail-users --forward bar@example.com --add-alias "!cat > /var/spool/mail/bar/whatever.mbox" Forwards can be listed using the same --list command as for users. For ex- ample, to see where the local address bar@example.com might be forwarded to, use the following: dbmail-users --list-user bar@example.com forward [bar@example.com] to [bar@example.net] forward [bar@example.com] to [|/usr/sbin/superspamtrapper] forward [bar@example.com] to [!cat > /var/spool/mail/bar/whatever.mbox] Forwards can be removed using basic glob style pattern matching. A ? ques- tion means "match zero or one of any character" and * asterisk means "match zero or more of any character." For example: dbmail-users --forward bar@example.com --delete-forward "*" will complete and totally remove the bar@example.com external alias and all of its forwarding addresses and commands. For example Gollum used to work at example.com but now works at example.org so any email addressed to gollum@example.com is forwarded to gollum@exam- ple.org dbmail-users --forward gollum@example.com --add-forward gollum@example.org When Gollum moves to example.net you delete the old forward and add the new one dbmail-users --forward gollum@example.com \ --delete-forward gollum@example.org \ --add-forward gollum@example.net SEE ALSO dbmail(1), dbmail.conf(5), dbmail-deliver(1), dbmail-export(8), db- mail-httpd(8), dbmail-imapd(8), dbmail-lmtpd(8), dbmail-pop3d(8), db- mail-sieved(8), dbmail-sievecmd(8), dbmail-users(8), dbmail-util(8) BUGS For the latest announcements, please subscribe to the DBMail announce mail- ing list[1] For general discussion, please subscribe to the DBMail general mailing list[2] If you experience an issue with DBMail, please report it on the DBMail Bug Tracker[3].
