[Mailman-Users] Mailman and Sendmail debugging questions

[Daniel, Barry K.]

Some background:
Machine A has Sun JES Messenger 6.2 running as the main mail server that points to the outside world.  I have installed the mailmanWrapper.pl program to interface Messenger with Mailman.
 
Machine B has the Mailman 2.1.8 installation, the JES Web Server, and Sendmail.
 
I have two problems.  First, if I create a new list via command line I cannot edit it via the web interface.  I execute the command line as the "mailman" user and the web is executed as the "webservd" user.  I have placed the webservd user in the mailman group in my /etc/group file but I still can not add users to the list via the web interface.  The lists/testlist/config.pck file changes date but the information does not change.
 
Second problem.  If I send an email to testlist at domain.com from the Sun JES Messenger it traverses to the Mailman machine but an email addressed to testlist at domain.com is sent back to the Messenger machine.  (This is from looking at the Sendmail logs.) Shouldn't it be sending back several emails, one addressed to each member of the list?  How do I debug this?
 
Thanks for any help.
