possible config error - masquerade

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 @gmx.de addresses, there comes the
following error in the mailforwarder:
Jan 24 09:14:08
dns-ssi postfix/nqmgr[27335]: F09B02CC2F7:
from=, size=762, nrcpt=1 (queue
active) Jan 24 09:14:08 dns-ssi postfix/smtp[30338]:
F09B02CC2F7: to=,
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:

How do I get rid of this?
I tried it with masquerading, so I added masquerading to my
sendmail.mc:

divert(0)dnl
VERSIONID(`@(#)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$* < @ $* .$m. > $* $#esmtp $@ $2.$m $: $1 < @ $2.$m. > $3


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

It is unclear what is version of sendmail.

It may be that root is not masqueraded.

In smart host log there is root@MW-Columbia.schaefer-shop.de
and not www@MW-Columbia.schaefer-shop.de

Check first that you have generated sendmail.cf from
that new sendmail.mc and restarted sendmail daemon.

Then test following
$ /usr/sbin/sendmail -bt
/tryflags ES
/try esmtp www@MW-Columbia.schaefer-shop.de
/quit


/ Kari Hurtta


8.10.0/8.10.0 2000/03/01
<...>
CONFIG: Removed root from class E; use EXPOSED_USER(`root')
to get the old behavior. Suggested by Joe Pruett
of Q7 Enterprises.

Hello Everyone,

here we go again.

1. I checked, that my actual sendmail.cf is the one created by me and
sendmail was restarted.

2. Version is 8.13.7+Sun/8.13.7

I tried it, but with some changes.
As user www I tried to masquerade as markus.boehmer@schaefer-shop.de
which is what I want:
/usr/lib/sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter

Why you are replaced "www" with "w..." ?

No, it is not.
Here is what I tried.

root@MW-Columbia> /usr/lib/sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter

Try

MASQUERADE_AS(`schaefer-shop.de')
MASQUERADE_DOMAIN(`schaefer-shop.de')
FEATURE(`masquerade_entire_domain')
FEATURE(`masquerade_envelope')

and send mail to someone outside.
