Mailman + Postfix - mail bouncing for mailing list

[rexregis]

Greetings, all! I have set up virtual email hosting as per this guide. I have also set up mailiman for some mailing lists. Somehow, I've missed something. When I attempt to send a message to the mailing list address, it bounces. The email is returned as follows:

[rexregis]

I also noticed that if I put a virtual alias (into either the virtual table in the mysql db or the virtual-mailman) for the mailing list email, the system will find that, but bounce the email anyway. However, I am not even trying to do a virtual setup. I just want one mailing list for the one domain for right now. So, I have taken out the entry in the virtual table. Now, when I try to send an email to the mailing list, the 'tail -f /var/log/messages' output is as follows:

[rexregis]

I finally discovered that what I had done wrong. Inside of my /etc/postfix/main.cf file, I had declared 'alias_database' and 'alias_maps' both twice. Once at the beginning, and once (which had already been put there before I ever touched the file) at the end. As many know, the last definition of a variable in the config files is the one that sticks. So, when I had declared them correctly at the beginning of the file, the re-declaration at the end (which was incorrect) of the file is the one that was used. So... if you are experiencing this problem, remember to check your variable declarations to make sure they are not declared twice.
