Tip: always keep your system and the programs on it patched and up to date.

Tip: You need to run with an opt code cache. eAccelerator is in the ports system
Tip: When using PHP, Perl, Python et. al. buy the fastest CPU you can.
Tip: Lots of RAM.

Tip: FreeBSD, Apache 1.3, and PostgreSQL.
IMAP is decentralized, the mail stays on the server. With POP3 the
client downloads the mail to a local system and that's that... An
example of IMAP would be webmail... IMAP can do a lot more too, It
blows POP3 out of the water. You can make IMAP work like POP3 too.
You should look into LDAP too.
