1839.0. "Mail problem" by NETRIX::"torsten.kerschat@beo.mts.dec.com" (torsten kerschat) Thu Mar 06 1997 11:45

Hi mail-experts,

when my customer sends a mail from his Firewall (AVFW 2.1) 
to an internal mail-user, the from line doesn't contain
the hostname (which should be in there). 
Furtheron, the "received from" contains only the external
firewall-hostname (fw) and not the FQDN... (internal name:
fw-gate). It is not configured to remove to the hostname.
Any ideas ? Here are the config files and the
contents of one the test-mails:

From:	MX%"root@subdomain.domain.de"  5-MAR-1997 12:50:43.14
To:	internal
CC:	
Subj:	

Return-Path: <root@subdomain.domain.de>
Received: from fw (fwgate.subdomain.domain.De) by bad.subdomain.domain.de (MX

I think you'll find this is how it's supposed to work.
