You can tell Outlook not to remove messages after reading them when using
POP3, but I don't know whether it will remove them just the same with
IMAP.

My configuration has wu.imapd and pop3d running from inetd.

There are many web based clients that work with IMAP and POP3, I have
found that squirrelmail is one of the best.  http://www.squirrelmail.org/

Most MTA (Mail Transport Agents) can do virtual mail handling, I use
Sendmail with virtusertable to map local users to virtual domains, for
instance:

mark at ascentium.co.uk          mark
mark at startinvesting.co.uk     mark
george at startinvesting.co.uk   george

I know that there are plugins for squirrelmail for handling .procmail rules.

Does the rules interface in Outlook do server side or just client side rules?

All I have mentioned above is free in both senses of the word.
