DESCRIPTION

       Esmtp  is  a  send-only  sendmail  emulator for machines which normally
       retrieve their mail from a centralized mailhub using programs  such  as
       fetchmail.

       Esmtp does not attempt to provide all the functionality of sendmail: it
       is intended to be used by mail user agents as mutt.

OPTIONS

       Most  sendmail  options  are  irrelevant  to  esmtp  .   Those   marked
       ‘‘ignored’’  or  ‘‘default’’  have  no  effect on mail transfer.  Those
       marked ‘‘unsupported’’ are fatal errors.

       -Ac (ignored)
              Use submit.cf even if the operation mode does  not  indicate  an
              initial mail submission.

       -Am (ignored)
              Use  sendmail.cf even if the operation mode indicates an initial
              mail submission.

       -B type
              Set the body type to type.  Current legal  values  are  7BIT  or
              8BITMIME.

       -ba (unsupported)
              Go into ARPANET mode.

       -bd (unsupported)
              Run as a daemon.

       -bD (unsupported)
              Same as -bd except runs in foreground.

       -bh (unsupported)
              Print the persistent host status database.

       -bH (unsupported)
              Purge  expired entries from the persistent host status database.

       -bi (ignored)
              Initialize the alias database.

       -bm (default)
              Deliver mail in the usual way.

       -bp    Print a listing of the queue(s).

       -bP (unsupported)
              Print number of entries in the  queue(s);  only  available  with
              shared memory support.

       -bs (unsupported)
              Use  the  SMTP protocol as described in RFC821 on standard input
              and output.

       -bt (unsupported)
              Run in address test mode.

       -bv (unsupported)
              Verify names only - do not try to collect or deliver a  message.

       -C file
              Use alternate configuration file.

       -d X (ignored)
              Set debugging value to X.

       -F fullname
              Set the full name of the sender.

       -f name
              Sets  the name of the ‘‘from’’ person (i.e., the envelope sender
              of the mail).  This address may also be used in the From: header
              if  that  header  is  missing  during  initial  submission.  The
              envelope sender address is used as the  recipient  for  delivery
              status  notifications  and  may  also  appear  in a Return-Path:
              header.

              This address is also used to select from different identities in
              the configuration file.

              If  no envelope sender is specified in the command line then the
              default identity’s address is used.

       -G (ignored)
              Relay (gateway) submission of a message.

       -h N (ignored)
              Set the hop count to N.

       -I (ignored)
              Same as -bi.

       -i (ignored)
              Ignore dots alone on lines by themselves in  incoming  messages.
              This should be set if you are reading data from a file.

       -L tag (ignored)
              Set  the identifier used in syslog messages to the supplied tag.

       -N dsn Set delivery status notification conditions to dsn, which can be
              ‘never’  for  no  notifications or a comma separated list of the
              values ‘failure’ to be notified if delivery failed,  ‘delay’  to
              be notified if delivery is delayed, and ‘success’ to be notified
              when the message is successfully delivered.

       -n (default)
              Don’t do aliasing.

       -O option=value (ignored)
              Set option option to the specified value.  This form  uses  long
              names.

       -o x value (ignored)
              Set  option  x  to  the  specified value.  This form uses single
              character names only.

       -p protocol (ignored)
              Set the name of the protocol used to receive the message.

       -q[time] (ignored)
              Process saved messages in the queue at given intervals.

       -qp[time] (ignored)
              Similar to -qtime, except that instead of periodically forking a
              child  to process the queue, forks a single persistent child for
              each queue that alternates  between  processing  the  queue  and
              sleeping.

       -qf (ignored)
              Process  saved messages in the queue once and do not fork(), but
              run in the foreground.

       -qG name (ignored)
              Process jobs in queue group called name only.

       -q[!]I substr (ignored)
              Limit processed jobs to those containing substr as  a  substring
              of the queue id or not when ! is specified.

       -q[!]R substr (ignored)
              Limit  processed  jobs to those containing substr as a substring
              of one of the recipients or not when ! is specified.

       -q[!]S substr (ignored)
              Limit processed jobs to those containing substr as  a  substring
              of the sender or not when ! is specified.

       -R return
              Set  the  amount  of  the  message to be returned if the message
              bounces.  The return parameter  can  be  ‘full’  to  return  the
              entire  message  or  ‘hdrs’  to return only the headers.  In the
              latter case also local bounces return only the headers.

       -r name
              An alternate and obsolete form of the -f flag.

       -t     Read message for recipients.  To:, Cc:, and Bcc: lines  will  be
              scanned  for recipient addresses.  The Bcc: line will be deleted
              before transmission.

       -V envid
              Set the original envelope id.

       -v     Go into verbose mode.

       -X logfile
              Log all traffic in and out of mailers in the indicated log file.

       --     Stop  processing command flags and use the rest of the arguments
              as addresses.
