Thank you for taking the trouble to explain something even though  
it's written in the docs in various places. I've got it working  
thanks to you. In case anyone else has this problem, (recovering from  
a sendmail addiction while moving from FC4 to FC5) I'm documenting  
what I did to get this working.

They were in /etc/aliases (the system-wide one). After I got the  
postfix-mailman alias file working I did need to remove them from the  
system-wide one. It took precedence over the postfix-mailman alias  
file, it seems.

This is a good start, but you also have to read /usr/share/doc/ 
mailman-2.1.8/INSTALL.REDHAT which tells you the directories mailman  
uses in FC5 have changed. Where once they were installed in /usr/ 
local/mailman, the binaries and what not are now in /usr/lib/mailman

Most importantly, the output of the genaliases command, once you've  
changed your mm_cfg.py file to set your MTA = 'Postfix', doesn't go  
to /usr/lib/mailman/data/ it goes to /etc/mailman/data/

So postfix's main.cf has to point to /etc/mailman/aliases in addition  
to any other alias files you need to parse, the system-wide aliases  
file cannot have any mailman list entries in it, and the mm_cfg.py  
file (also found in /etc/mailman) has to specify MTA =  
'Postfix' (case sensitive).
