Exim is I/O limited - so you have to work on increasing disk I/O speed. A
fast SCSI hard disk or two (and possibly a RAID setup) would be great for
lighter loads. For heavier loads, a journaling filesystem, a ramdisk or two
... the sky's the limit. Then there's queue management (multiple queues on
different machines, sets of backup MX servers etc)
See Dr.Yann Golanski's paper on this at
http://www.kierun.org/academic/lsm.tar.gz (LaTeX)
http://www.kierun.org/academic/lsm.pdf.gz (PDF)
He's a senior developer of Exim, and a former admin at Planet Online /
Freeserve, one of the UK's largest ISPs (the paper above gives some details
re the setup he implemented at Freeserve)
Thing is, that's for pushing a few _million_ mails a day. If you want a few
thousand, a comp with a fast scsi disk (and a reasonably fast processor,
decent RAM etc) would do.
Ask on [EMAIL PROTECTED] - I suppose Yann would give a personal reply to
this q (or search the archives ... he's posted about this hajjaar times) :)
