We run Exim on our main MX machine (30,000 messages incoming a day,
expands to [latest peak] 38,000 delivered messages). Used to be a
SPARC Classic!! (buckled) now a SPARC Ultra1 with 64MB RAM,
expecting delivery of a larger server (200MHz+128MB) in a few weeks.
On Solaris Exim works splendidly, however we serve POP users on
Linux boxes and these are proving to be a bit of a problem, but in
general there appear to be many bugs in the Libux Kernel that
surface under heavy load.

I'm keen to understand how you have arranged the SPARCServer 1000s
in such a configuration. In my previous job we had 2x4proc 1000s
but the only way to tie them together was with Sun's HA s/w, which
at R100K (about $25K) we were somewhat reluctant and rather just ran
the second machine as a hot spare, occasionally manually segmenting
work to farm out to it (100mbps ethernet made NFS _real_ quick! :-)
Do you just break your users into 2 clumps and point some at the one
machine and some at the other?

also can you tell me what config machine is handling a load of
10,000 users? What POP / IMAP s/w are you using? (It seems you are
now running exim, so were there any funnies about mail directory
delivery -- some POP servers don't necessarily read from
/var/mail/username, but rather /var/mailbox/user_name/msg_id[1-n])

he-he, can you spell "pay-cheque" :-)
