Apart from the slowness of the Imail box's CPU and apparent sluggishness in
its daily rounds, you could/will have a huge buildup of incoming mail
queued in the \spool directory, I "think". I'm not sure but I think it's
the "SMTP client" process that delivers the mail and applies the filtering
to msgs that have been unfilteredly accepted by the SMTPD server process
and queued for delivery. If I'm guessing right, then the "SMTPD server"
processes that receive the incoming will be dumping the mail to the queue,
requiring disk space, and for some time, before the SMTP client processes
pick up the mail and apply the filtering.
So make sure, for the 1000+ rules project, that you have plenty of disk
space for the "incoming msgs queued for filtered delivery" traffic. Also,
I guess that you will need to allot more SMTP processes and RAM since the
filtering will keep every SMTP process alive in memory longer.
I keep thinking of a cartoon of a garden hose with kink in it causing a
HUGE balloon. vbg
