Doing great work ??

telnet mail-abuse.org
...
Relay test 11
>>> RSET
<<< 250 2.0.0 Ok
>>> MAIL FROM:<spamtest@testhost.domain.com>
<<< 250 2.1.0 Sender syntax Ok
>>> RCPT TO:<"relaytest@mail-abuse.org"@testhost.domain.com>
<<< 250 2.1.5 Recipient address syntax Ok
Relay test result
Uh oh, host appeared to accept a message for relay.
The host may reject this message internally, however
Connection closed by foreign host.

However, the mail didn't reach relaytest@mail-abuse.org. Instead
spamtest@testhost.domain.com got it back stating
"relaytest@mail-abuse.org" is not a user on this host.

I get the idea that by failing this test some spamfighters (i.e. ORBS)
think you're still vulnerable, thus don't remove you from their database.
But the host doesn't relay !
