All outbound mail from Mailman goes through your MTA - Postfix in your case.
What do the Postfix logs report about the mail to the support and/or sales
mailboxes?  Check the Postfix configuration to see what alias files 
Postfix is
reading.  Maybe you have an "unknown" alias file that routes support and 
sales
somewhere else?  And check that "postalias" has been run on all of the alias
files.
