Peter,
I think most of your questions have been covered but I'll give you my 2
cents from experience. I run a mail server for an isp w/ over 4k mail
spools. One thing that helped us out that both cucipop (for sure) and
qpopper (so I'm told) will let you do is to hash /var/spool/mail so as
not to have so many files in one dir. In other words user "foo" would
have mail in /var/spool/mail/f/o/ . Other than that:
Don't skimp on ram, go for 512MB
Don't skimp on controller, get Buslogic
I have a script to create the hashed dir structure. Let me know if you
decide to go that route and I'll send it your way.
Good luck!
