PLEASE HELP! I'm at my wits end!!!

BACKGROUND:

I am running Red Hat Linux 9 on a Dell PowerEdge Server i686.

I was using Qmail, but I didn't like it. It would periodically cause some issue
that would leave my queue all messed up. Finally, I took the plunge and
researched alternatives. I came across Courier/Postfix. Yesterday, I deleted
everything on my machine related to Qmail and proceeded to install a new
solution.

OBJECTIVE:

To run Courier/Postfix with SASL Authentication, MySQL Integration,
Maildrop/SpamAssassin, and connectivity via IMAP and POP3. The directory
structure I have chosen to implement is the Maildir style - all mail goes into
/home/postmail (plus the normal domain name/email address folders).

CURRENT ISSUES:

I believe I've installed everything correctly, after almost ten hours of
installing packages, patching problems, reading tons of information, etc., but I
cannot get maildrop to deliver any mail - depending on the mailbox, it either
cannot set the uid/gid, or it cannot open the mailbox. I cannot figure out how
to view the queue or to ask it to send it again. In addition, I cannot connect
remotely to IMAP, and I don't seem to have POP3 installed, or I cannot figure
out how to turn it on!

INFORMATION USEFUL TO DIAGNOSE PROBLEMS

Please let me know what information would be appropriate to post in order to
help diagnose the problems I am having - including any commands that would
supply this information. I'm unsure where to start. If anyone can help me,
please let me know. Thank you in advance for your assistance!
