hi,

we had an email from a domain named tntpost.co.uk

the email got rejected several time by our sender id spam filter.

because of the below in the edge server agent log.


2009-10-26T15:25:01.369Z,08CC21785036791B,DELETED,85.119.248.30:55897,85.119.248.30,,DELETED@tntpost.co.uk,DELETED@tntpost.co.uk;,DELETED@tobar.co.uk,1,Sender Id Agent,OnEndOfHeaders,RejectMessage,550 5.7.1 Sender ID (PRA) Not Permitted,Fail_NotPermitted,DELETED@tntpost.co.uk,

(DELETED denotes rpivate and confidential info and not actually in log)


however when using test-senderid command in exchange shell it appears to pass the test?

i used the ip address from network-tools external website to verify the ip address and used this when using test-senderid.

any ideas why spam filter is picking up this particular email?

would it be because at the time of recieving the email the domain could not be resolved.

any help would be great thanks.
