NAME
     whom - show to whom an nmh message would be sent

SYNOPSIS
     whom [-help] [-version] [-alias aliasfile] [-check | -nocheck] [-draft-
	  folder +folder] [-draftmessage msg] [-nodraftfolder] [-mts smtp |
	  sendmail/smtp | sendmail/pipe] [-server servername] [-port port-
	  name/number] [-sasl] [-saslmech mechanism] [-snoop] [-user username]
	  [-tls] [-initialtls] [-notls] [file] [-draft]

DESCRIPTION
     whom is used to expand the headers of a message into a set of addresses and
     optionally  verify  that  those  addresses are deliverable at that time (if
     -check is given).

     The -draftfolder +folder and -draftmessage  msg  switches	invoke	the  nmh
     draft  folder  facility.	This is an advanced (and highly useful) feature.
     Consult mh-draft(5) for more information.

     The   mail   transport   system   default	 is   provided	  in	/usr/lo-
     cal/etc/nmh/mts.conf but can be overridden here with the -mts switch.

     If  nmh  is  using  the SMTP MTA, the -server and the -port switches can be
     used  to  override  the  default  mail  server  (defined  by  the	/usr/lo-
     cal/etc/nmh/mts.conf servers entry).  The -snoop switch can be used to view
     the  SMTP	transaction.   (Beware that the SMTP transaction may contain au-
     thentication information either in plaintext or easily decoded base64.)

     If nmh has been compiled with SASL support, the -sasl  switch  will  enable
     the  use  of  SASL authentication with the SMTP MTA.  Depending on the SASL
     mechanism used, this may require an additional  password  prompt  from  the
     user  (but  the netrc file can be used to store this password, as described
     in mh-profile(5)).  The -saslmech switch can be used to select a particular
     SASL mechanism, and the -user switch can be used to select a  authorization
     userid  to provide to SASL other than the default.  The credentials profile
     entry in mh-profile(5) describes the ways to supply a  username  and  pass-
     word.

     If SASL authentication is successful, nmh will attempt to negotiate a secu-
     rity  layer  for session encryption.  Encrypted data is labelled with `(en-
     crypted)' and `(decrypted)' when viewing  the  SMTP  transaction  with  the
     -snoop switch; see post(8)'s description of -snoop for its other features.

     If  nmh  has  been  compiled  with  TLS support, the -tls, -initialtls, and
     -notls switches will require and disable the  negotiation	of  TLS  support
     when connecting to the SMTP MTA.  Encrypted data is labelled with `(tls-en-
     crypted)'	and `(tls-decrypted)' when viewing the SMTP transaction with the
     -snoop switch; see post(8)'s description of -snoop and the  TLS  flags  for
     more details.

     The  files  specified  by the profile entry "Aliasfile:" and any additional
     alias files given by the -alias aliasfile switch will be  read  (more  than
     one file, each preceded by -alias, can be named).	See mh-alias(5) for more
     information.

FILES
     $HOME/.mh_profile			  The user profile

PROFILE COMPONENTS
     Path:		  To determine the user's nmh directory
     Draft-Folder:	  To specify the default draftfolder
     Aliasfile: 	  For a default alias file
     postproc:		  Program to post the message

SEE ALSO
     mh-alias(5), mh-draft(5), mh-profile(5), post(8)

DEFAULTS
     `file' defaults to <mh-dir>/draft
     `-nocheck'
     `-alias' defaults to  /usr/local/etc/nmh/MailAliases

CONTEXT
     None

BUGS
     With  the -check option, whom makes no guarantees that the addresses listed
     as being ok are really deliverable, rather, an address being listed  as  ok
     means  that at the time that whom was run the address was thought to be de-
     liverable by the transport service.  For local addresses, this is absolute;
     for network addresses, it means that the host is known; for uucp addresses,
     it (often) means that the UUCP network is available for use.
