Hello everyone,
this is our network in short.
One Mailforwarder, which is reachable from the outside.
One Server behind our firewall, from which I want to send mail, this
one has solaris 10 and sendmail installed.
I configured the Mailforwarder as smart relay host, which works, but
when I want to send mails to [at] gmx.de addresses, there comes the
following error in the mailforwarder:
Jan 24 09:14:08
dns-ssi postfix/nqmgr[27335]: F09B02CC2F7:
from=<root [at] MW-Columbia.schaefer-shop.de>, size=762, nrcpt=1 (queue
active) Jan 24 09:14:08 dns-ssi postfix/smtp[30338]:
F09B02CC2F7: to=<boehmerm [at] gmx.de>,
relay=mx0.gmx.net[213.165.64.100], delay=1, status=bounced (host
mx0.gmx.net[213.165.64.100] said: 550 5.1.8 Cannot resolve your domain
{mx019} (in reply to MAIL FROM command))
OK...so gmx can't find our mw-columbia, which is okay, because it is
only in inside network.
So I had a look at the mailheaders, and there was the following line:
Return-Path: <www [at] MW-Columbia.schaefer-shop.de>
How do I get rid of this?
I tried it with masquerading, so I added masquerading to my
sendmail.mc:
<begin sendmail.mc>
divert(0)dnl
VERSIONID(` [at] (#)sendmail.mc 1.11 (Sun) 06/21/04')
OSTYPE(`solaris8')dnl
define(`SMART_HOST', mail.schaefer-shop.de)dnl
FEATURE(`relay_hosts_only')dnl
MASQUERADE_AS(`schaefer-shop.de')
FEATURE(`masquerade_envelope')
MAILER(`local')dnl
MAILER(`smtp')dnl
LOCAL_NET_CONFIG
R$* < [at] $* .$m. > $* $#esmtp $ [at] $2.$m $: $1 < [at] $2.$m. > $3
<end sendmail.mc>
But still the Return-Path is written as above.
I hope someone can give me a hint.
If you need further Information, please let me know.
Thanks
Markus
