Hmmm... anything unusual (ie to do with domains not local to your machine)
in /etc/mail/local-host-names or /etc/mail/virtusertable or
/etc/mail/mailertable? You're definitely running with that config file,
and you don't have anything like OpenBSD spamd(8) running that could intercept
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 connecting
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 using
an address that was somehow actually valid on your system.
