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 the mh-draft(5) man page for more information.

       The  mail transport system default is provided in /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
       /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 the mh-profile(5) man page).  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  the  mh-profile(5)  man
       page 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 the post man page 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  the post man page 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 find the default draft-folder
       Aliasfile:           For a default alias file
       postproc:            Program to post the message

SEE ALSO

DEFAULTS
       `file' defaults to <mh-dir>/draft
       `-nocheck'
       `-alias' defaults to  /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.
