HI All,

I got the following error after I post my first mail to the list. I am using
Sendmail. I don't know what to do.

Servername Mailman mail-wrapper: Group mismatch error.  Mailman expected the
mail wrapper script to be executed as group "mailman", but the system's mail
server executed the mail script as group "mailnull".  Try tweaking the mail
server to run the script as group "mailman", or re-run configure,  providing
the command line option `--with-mail-gid=mailnull'.
