Misconfigured mailserver
Posted: Mon Aug 30, 2004 8:59 pm
Your mailserver is claiming to be 'web01', but doesn't mention any domain.
According to the RFC, a mailserver should not accept mail from such a server.
What this means, is that a lot of people won't be able to register because they never receive the activation email because their ISP denies mail from servers that do not exist.
Spammers use this technique all the time, which is partly why this policy exists.
