Description of problem:
I have setup a few virtual domains via the linuxconf tool.
Aliases for mailman lists are declared in /etc/vmail/aliases.domain.tld

Then all email sent to the list are not computed by mailman and the error 
messages in /var/log/maillog is :

Mailman mail-wrapper: Failure to exec script. WANTED gid 12, GOT gid 
65535. (Reconfigure to take 65535?)

How reproducible:
Always

Steps to Reproduce:
1. Install mailman RPM and then create a list
2. Copy the given aliases in /etc/vmail/aliases.domain.tld
3. Send a mail to thelist
4. See the error in the maillog file
	

Actual Results:  Mailman mail-wrapper: Failure to exec script. WANTED gid 
12, GOT gid 65535. (Reconfigure to take 65535?)

And of course nothing is processed by mailman.

Expected Results:  The email should have been sent to the list

Additional info:

mailman is working well on the main domain of the machine.
