I am setting up a small mail server. Postfix, on Fedora, with about 25 accounts, so no need for MySQL, no need for IMAP, all we need is a simple POP server. Postfix works sending mail to different user accounts on the computer, but now what. Are there any good tutorials out there? Do i need a local DNS as well as the DNS entry my ISP will give me?Do i need a local delivery agent? Any help is much appreciated.
