I have an odd situation that I have not noticed before.
In my RCPT ACL I do 'verify = sender/callout' and record the result for spam-scoring later.
In my DATA ACL I do 'verify = header_sender' (note: with no callout).
I have messages with both an envelope sender and a header From: of westlaw@???.
If you do a callout for westlaw@??? you get a failure.
The 'verify = header_sender' should not fail because westlaw.co.uk is a registered domain and has MX records. However, it is failing and so the messages are being rejected with 'no valid sender in any header line'.
I can only assume that the result of the 'verify = sender/callout' is being cached and used to cause the 'verify = header_sender' to fail as well.
Can anyone confirm that this is indeed the case. If it is then surely it is a bug because the options are different in the two cases.
If the header_sender is not failing because of a cached result then I am mystified as to why it is failing!
Thanks for any comments,
Phil.
