Completely guessing here, but it looks like the RaQ can't verify whether or
not this host is "genuine", and therefore isn't allowing connections. The
RaQ does have a built-in type of security where it won't allow connections
through sendmail if a domain doesn't exist - quite useful in rejecting spam
where the spammer has forged a fake email addy. I think that might be coming
in to play here. Sendmail can't get the name of the host, therefore it can't
determine if it's a "real" host/domain, so it's not allowing the connection.
Like I said, completely guessing. I'm still learning how to read my error
logs too. :)
(Anyone got a good webpage for explanations of log messages?)
