  The error message itself is essentially correct. However, what this
  really means is: MH's post cannot connect to a running sendmail over
  an SMTP port (MH configured with SMTP and SENDMTS).

  The potential problems:

  1. Your local sendmail daemon is dying or not running for some
     reason.

  2. You use BIND and your local nameserver is not responding.
     Solution: Delete "/etc/resolv.conf."

  3. Your $MHLIB/mts.conf (mtstailor) has its "servers:" pointing to a
     non-existent machine or a machine which is a) not reachable or b)
     not running the sendmail daemon.

  4. The hostname localhost [127.0.0.1] is missing from /etc/hosts.

     Solution: add an entry for "localhost" to /etc/hosts or your DNS
     database or add the following to $MHLIB/mts.conf (mtstailor):

       servers: 127.0.0.1 \01localnet

  5. Your load average is so high that sendmail is refusing
     connections.

     Solution: Change your configuration from "mta: sendmail/smtp" to
     "mta: sendmail" so that a sendmail processes is spawned to
     deliver the message. This is a double-edged sword since the extra
     process only makes the load worse.

  6. Sendmail may not be located on the path that MH expects.

     Solution: Try specifying the path explicitly by adding a line to
     mts.conf thus:
  
       sendmail: /usr/sbin/sendmail
  
     or wherever your sendmail daemon executable lives.

  7. You don't want to use an available server.

     Solution: Try

       postproc: /usr/local/lib/mh/spost

     in your MH profile (but check the path first). That should use
     command line sendmail.
