[Mailman-Users] Migrating lists

I have a number of mailman lists that I'm attempting to migrate from an 
older OpenBSD server running Mailman 2.1.2 to a new RHEL server running 
Mailman 2.1.5.  I built the new version from source, setting the 
mail-gid (postfix) and cgi-gid (apache) accordingly.  I then copied 
over everything in /var/spool/mailman and set permissions for mailman 

Unfortunately, it appears that the mailing lists will need additional 
manipulation to get them working properly.  I'm seeing the following 
errors when sending test mails to a list:

Diagnostic-Code: X-Postfix; Command died with status 2:
     "/usr/local/mailman/mail/mailman post hatchet-users". Command 
output: Group
     mismatch error.  Mailman expected the mail wrapper script to be 
executed as
     group "postfix", but the system's mail server executed the mail 
script as
     group "nobody".  Try tweaking the mail server to run the script as 
     "postfix", or re-run configure,  providing the command line option

What can I do to resolve this?  Do I need to manually dump/restore list 
configurations from the old server (if so, how)?

Thanks in advance,
