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 user-
	    name] [-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)  fea-
       ture.  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  con-
       tain  authentication  information either	in plaintext or	easily decoded
       base64.)

       If nmh has been compiled	with SASL support, the -sasl switch  will  en-
       able  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  de-
       fault.	The  credentials  profile entry	in mh-profile(5) describes the
       ways to supply a	username and password.

       If SASL authentication is successful, nmh will attempt to  negotiate  a
       security	layer for session encryption.  Encrypted data is labelled with
       `(encrypted)'  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-encrypted)'  and `(tls-decrypted)'	when viewing the SMTP transac-
       tion 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 addi-
       tional 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	deliverable  by	 the transport service.	 For local ad-
       dresses,	this is	absolute; for network addresses,  it  means  that  the
       host  is	known; for uucp	addresses, it (often) means that the UUCP net-
       work is available for use.
