[Mailman-Users] sendmail problem - User unknown

[clay at hsdglobal.com]

I just installed mailman on Redhat Linux 8.0. Since I saw no documentation
for the RPM version included, I uninstalled that and went the manual way.
I installed with: ./configure --with-cgi-gid=apache. My web pages work
fine. I did see an option for --with-mail-gid. I did not use that as I did
not know the gid for sendmail. I looked in /etc/passwd and did not see a
user "sendmail". When I create a list, I get an email sent. I assume that
the message is being sent from the shell. When I try to send a message to
the list I created I get this reply:
