  This was a deliberate design decision.  Zmailer never removes
duplicates.

  I think Rayan liked having all the header lines line up.  If you look in
./router/conf.c there is a "wanttabs" variable that you can set to 0.

  expn and vrfy can be quite expensive in Zmailer, so I normally disable
their use.  There is a command-line option that tells the smtpserver to
enable vrfy/expn.  The smtpserver actually handles an expn/vrfy request by
forking a router,and execs server() in server.cf

  This would be compiler dependant.  Is this the Sunsoft or GCC compiler?
(I guess Sunsoft...)

  This isn't needed.  The scheduler will not attempt to establish more
than one smtp connection at a time with any particular host.
