RE: Rewriting headers

["Alfredo Sanjuan" <alfre@ibd.es>]

The normal behaviour of the Zmailer is to rewrite things in the header section
of the messages when it recognices the domain in the "From" header as a
localname. I want that the behaviour of the Zmailer with these kind of messages
was the same as domains listed as "allow relay" in the policy rules. That is, no
rewrite at all, and log them in the maillog with the original domain, not with
the domain of the Zmailer relay machine. But we want to continue aceppting mail
for these domains...

I don't know if this is possible hacking the configuration files.
