Hi folks I was wondering?
Does mailman and sendmail have to run as the same user?
I am working on a yellowdog 3 system trying to get mailman to work and
im stuck on one spot
the errors i keep getting are this
messages sent to the list are bouncing at the mailserver (sendmail
lists creation works ok and initial email subscribe (outbound mail)
works ok
web interface works ok
a look at  /var/log/maillog logs shows this:
Mailman mail-wrapper: Group mismatch error. 
Mailman expected the mail wrapper script to be executed as one of the
following groups:
 [mail, nobody, mailman], but the system's mail erver executed the mail
script as group: "mailnull". 
Try tweaking the mail server to run the script as one of these groups:
[mail, nobody, mailman], 
or re-run configure providing the command line option:
We are running Mailman version 2.1.1
Any help is appreciated
