I just upgraded to sendmail 8.9.3 (downloaded the rpm from
the contrib directory)
As I've read this version should deny relay by default,
however in my case it allows relays from everywhere!
I've set up an access file in /etc/mail and runed makemap
and it even ignores a REJECT line in there.
I would really appreaciate if you could help me out since
this is a rather bad situation because of spammers...
Sorry, we don't officially support anything in the contrib
directory. The packager is free to configure packages uploaded to
contrib as they see fit.
