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.
