Application Development Software

Hi all,

I have a problem with a Messaging Server (Sun Java(tm) System Messaging Server 6.2-7.05 (built Sep 5 2006)) running on Solaris 10 SPARC .

Every outgoing mail seems to get an additional Return-Path header with the sender address, even when there is already an identical one. The problem is that the remote server does not really like that since this is a closed system with a strict inter-server communication protocol which does not allow for more than one return-path in the mail source (can't help about that).

This is an excerpt from the mail.log :

And this is the configuration relevant to the tcp_relay and tcp_local channels:

-----
imta.cnf :
rewrite rules
! tcp_local
! Rules for top level internet domains
<IMTA_TABLE:internet.rules

channels:

Any help would be really appreciated!

Many thanks in advance.
