Re: rfc822 header canonicalization

["Mariano Absatz" <zmailer@lists.com.ar>]

Hi... I got no answer to this e-mail... so I'm trying to understand it by 
myself... with little success :-(

What I'm trying is to manage messages received from internet that pass-thru 
this server. I don't care (much) about locally generated messages (these are 
working fine) or locally addressed messages (there are not such, _everething_ 
goes somewhere else).

How do I avoid rewriting of rfc822 "From:" header when there's no domain in 
there?

At least a couple of pointers would be nice... I'm reading the "internet()" 
function in cf/crossbar.cf, but I don't know what to do.

The manual isn't too helpful either:
http://zmailer.org/zman/zref-router.shtml#ZMSHREF.WKE.CROSSBAR
:-(

I'd be greatly thankful for any pointers.

Regards.
