I recently began using SMTP via a mailer which uses Aegis
mailboxes.  The mailer is invoked using:

   Mmbx, P=/usr/lib/mailer/mbxsmtp, F=msDFMuCX, A=mbxsmtp -n //$h           

Firstly:

   I'd like to know if anyone else uses SMTP via a mailer (not [IPC]).
   I'd like to get a description of what the mailer uses to support SMTP.

Secondly:

   Occasionally, the mailer fails due to various problems and exits with
   a status of EX_TEMPFAIL	which is 75, which means that sendmail is
   supposed to try again later.

   Unfortunately, sendmail returns a copy of the message when the mailer
   exits with a "75" even though it does requeue the message.  The message
   I get looks like this:

      Received: by apollo.UUCP id AB10811; Thu, 7 Jul 88 16:28:56 edt
      From: MAILER-DAEMON (Mail Delivery Subsystem)
      Subject: Returned mail: Deferred
      To: jlb
      
         ----- Transcript of session follows -----
      451 jlb@mc.lcs.mit.edu... reply: read error
      554 smtpquit reply error: stat 75
      
         ----- Unsent message follows -----
      Received: by apollo.UUCP id AA10811; Thu, 7 Jul 88 16:28:56 edt
      ...

   Does anyone know how to stop the returned messages (or is this the
   way bsd4.3 sendmail is supposed to work)?

Finally:

   What mailer flags do you use with your SMTP mailer (again, not [IPC])?


Thanks in advance for your help,
