Use the one you prefer. Personally I use slackware 4.0

For IMAP and pop, people told me that the cyrus suite is a great tool.
For the MTA I strongly recommand postfix : it has been build to be secure
and easily administrated. Whereas sendmail is one big suid root program,
postfix is devided in 10 and all can be chrooted and runed as postfix user
except the local deliverer which has to be suid and access to all yours
disks.
The only one problem with postfix is to change yours aliases database from
sendmail to the virtual database of postfix to avoid that mails are doubled.

Depends a lot of the number of users and the traffic.
A first price PC should be enough. For the disks it depends on yours users
and on the policy of your enterprise.
64Mo of RAM should be enough, but 128 isn't too much

Keep your deamons uptodate (see the bind 8.2.2 vulnerabilities).
SMTP, DNS, POP and IMAP are the most attacked protocols nowadays...
Chroot and use unprivileged users for every daemon, for DNS see :
http://www.psionic.com/papers/dns/
For postfix see its documentation : it's too easy ;-)
