Problems with 2 Email servers

Markus Wasse
Hello!
I have two Mailservers behind my Astaro 2.022.
One handles tms-tobacco.de and the other handles
cos-boga.de.
It works to send Emails from outside to wasse@cos-boga.de.
But when I send Emails from markus.wasse@tms-tobacco.de to wasse@cos-boga.de
I get:

Hi. This is the qmail-send program at TMFW001.tms-tobacco.de. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out.

:
Connected to 212.221.193.126 but sender was rejected.
Remote host said: 553 5.1.8 ... Domain of sender address markus.wasse@tms-tobacco.de does not exist

Has anyone an idea?
(The mailserver for cos-boga.de is sendmail from Suse Linux 7.3)

Thanks in advance

    This Suse box obviously has sender address checking enabled.

    Sendmail tries to find either an A or MX record for tms-tobacco.de, and does not find one.

    There may be two reasons:

    - tms-tobacco.de does neither have an A or MX record
    - The Suse box has no proper DNS resolution

    You can either fix those problems or disable the sender address checking in sendmail.cf


    cheers,  [;)]

    Thanks, it works with MX-record.
