Sendmail relay via ESMTP doesn't work

[WolfgangBauer]

Hi Guys,

I've a little bit greater problem than simple smtp-forwarding.

I've an sendmail with integrated Kaspersky Anti-Virus.
The machine should get the emails for domain.tld, check it with kaspersky and forward it to an Exchange Server.

In the acutal configuration it works without problems.

But NOW: When the sender sends an email to an unknown user, the exchange server replies following:

Following Receipients cannot be reached:

test@exchange.domain.tld at 11/25/2003 4:58 PM

Now theres our problem:
Sendmail forwards the email not only with the domain, he has an entry in the sendmail.cf which looks like this:

# place to which unknown users should be forwarded
Kuser user -m -a<>
DLesmtp:exchange.domain.tld.

It seems, that the mailertable is overwritten by this option. But the mailertable option is correctly set in the sendmail.cf and in my mailertable file, the esmtp forward is set correctly (yes, also makemap hash is done)
When I turn off this &quot;DLesmtp&quot;-Option, nothing works, he says &quot;User cannot be found&quot;

Does anyone knows what this DLesmp: does?
