Hmmm... anything unusual (ie to do with domains not local to your machin= e) in /etc/mail/local-host-names or /etc/mail/virtusertable or=20 /etc/mail/mailertable? You're definitely running with that config file, and you don't have anything like OpenBSD spamd(8) running that could inte= rcept incoming SMTP traffic? If that's so, then I can't see how your machine could be an open relay. = The abuse.net relay tester must have been having a bad day. In fact, can you= find the records in /var/mail/maillog to show abuse.net's server connecti= ng to yours in order to do the testing? It may be that it was connecting to= somewhere else entirely. Or it was somehow trying to test relaying usin= g an address that was somehow actually valid on your system.
