When I tried to send a message to all customers simultaneously, the number
of queued messages grew to 70.000 on a Solaris box. According to the mrtg
graphs, qmail was still operating quite efficiently.
(on a side note, any clues on what would be the best way to send mail to lots
of people located on a limited number of servers?)
Your filesystem matters a great deal. If you decide to use ext2 (linux)
without the sync-patches, your performance will be staggering. This at the
cost of losing mail in case of a crash.
Solaris UFS is incredibly slow and might run into performance problems when
queueing a number of messages which Linux (or BSD with softupdates for that
matter) would handle just fine.
UFS is however a very safe choice for guaranteeing the arrival of each and
every message, even in the case of a crash.
I'm not yet sure, but it appears it can be a big gain to have
/var/qmail/queue on another filesystem then your actual Maildirs.
