I've read many, many places that as of v8.9.3, sendmail does not relay by default.
Yes, this is true. I am using SuSE's Sendmail 8.12.3 and it passes all the test at: http://www.abuse.net/relay.html All the domains and hosts that are allowed to relay are now put in /etc/mail/relay-domains.
To my surprise, I was informed by a relay testing server that I was running an open relay, and, sure enough, my sendmail DOES relay.
This is really strange, do you have a proxy or a forwarder sitting between the Internet and the mailer daemon? This will give false positives, I can attest to that first hand. You might also want to check your sendmail.cf to see if for some strange reason: promiscuous_relay is turned on.
I had a line "127 RELAY" in /etc/mail/access,
This line is a default and does not affect things. If you want to you can send me your sendmail.cf and submit.cf and see if I can find anything. Charles -- "Nature abhors a Vacuum" -- Brian Behlendorf on OSS (Open Sources, 1999 O'Reilly and Associates)
