550 550 5.7.1 Message rejected as spam by Content Filtering. (state 18).

Hi,

Forwarding two gmail accounts email to an SBS 2008 , one works fine, the other gets following errors on some emails forwarded:

Subject: Delivery Status Notification (Failure)

Delivery to the following recipient failed permanently:

    name@domain.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 Message rejected as spam by Content Filtering. (state 18).


Using SBS 2008 with MS Forefront

Thanks,

state 18 - What is the meaning of the state 18?
where can i get states listed?
"state 18" is one of those fun google mysteries; useless information that generates hundreds of queries on their  support forums, with no answer forthcoming from google support, if there is any such department at google.  It is non-standard, i.e.. not defined by any RFC.  "550 5.7.1" (which IS defined) means "Delivery not authorized, message refused".

And to make things more fun, I have seen smtp logs where google connects, says EHLO, announces the sender and recipient, then drops the connection and reports back to the sender  "Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 Requested action not taken: message refused (state 18)".

So maybe "state 18" means google's servers are just too busy to deliver your message.
The answer is it tells you right there. What a joke. Easy free points to the expert. The solution has no direction on how to fix it.
