I think my sendmail is not correctly set. It says the default is to disallow relaying. I am running centos 4.8 and I think sendmail is relaying for anything.
Based on this: http://www.sendmail.org/~ca/email/chk-89f.html#RELAYING
I added|: FEATURE(relay_hosts_only) to my sendmail.mc file and restarted sendmail. I am still seeing connects that get relayed and are not in my /etc/mail/access file.
I assume that means you got a rebuilt sendmail.cf before restarting sendmail, but you'll want to make sure.
I also assume that you've defined the access_db feature in your sendmail.mc file.
That said, I don't include the relay_hosts_only FEATURE at all. I just add the IP addresses of the hosts that can relay into the access file, e.g.,
1.2.3.4 RELAY
Works for me.
