NAME

       whom - show to whom an nmh message would be sent

SYNOPSIS

       whom [-help] [-version] [-alias aliasfile] [-check | -nocheck] [-draftfolder +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 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
       contain authentication 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 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  transaction  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 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.

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
       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.
