configuring with postfix

[Matt Schwartz]

Hi, 

I really appreciate the help that everyone has been giving me.  I have 
gotten very far with using Cyrus IMAP and I must say it is heads above 
courier, the one I used to use.  I have one nagging issue and all will 
be straight.  I would like to make it easier for users posting to a 
shared folder.  For example, bb+public.announcements, they might type 
announcements instead.  I have tried to do this with postfix but to no 
avail. The message keeps getting bounced.  How do I configure postfix 
such that it expands the alias announcements into the full name of the 
public folder?  I apologize if I have the wrong list.

Thanks,
Matt
