[Mailman-Users] Sendmail issues with mailman

[Gordon Dahlby]

I have had issues with my sendmail being an open relay, so I have tighten
down security.  While I know this is not your organizations responsibility,
I was wondering if anyone else had ideas.

 

The maillist is being treated as a send mail user and my Sendmail is
rejecting it as the "user" is not known.

 

Any thoughts?   {Thank you in advance for your time.}
