A nice test to check if your machine isn't an open relay is opening a
telnet session to mail-abuse.org from the machine you want to test.

Although it doesn't seem to work now:

einstein:~# telnet mail-abuse.org
Trying 204.152.186.193...
Connected to mail-abuse.org.
Escape character is '^]'.
/proj/maps/bin/in.relaytest: socket failed [Bad file descriptor]


But it usually is a nice test... we use it at the ISP I work for to test
every colocated machine which is placed.
