¿Can one suggest a how-to on building a mail server?

I have been away from Linux for a couple of months but am now back with a vengeance. I have installed SuSE 8.2 Pro w/o problems and wish to set-up fetchmail/postfix and/or cyrus. Whenever I have done this before, I have used the postfix aliases database to distribute incoming mail. Is there an alternative which would allow my users to define their own aliases? Also, how could I automate the distribution of each users mail to their IMAP folder (once I have that set up correctly)? If these questions are a bit vague, please forgive me and point me to a suitably hand-holding how-to or other documentation. Thanks in advance -- Sylvanus A.
