Hello again,

the topic does not start a wild discussion :-) I thought again about comparable problems
and how they are solved there. Postfix for example give always a detailed logging on any problem.
But: the SMTP response is most times only "Server configuration error" or "recipient rejected".

Same would be reasonable here. Log, which header causing trouble but mention only "not RFC compliant" as SMTP reply.
I think, thats what Murray suggested too.

Btw: logging non confirming messages should be activ always. Rejecting them should be selectable, default off.
