[cobalt-users] Help with DNS MX (mail record) setup in a unusual configuration Qube3

[Jakob Strebel <mail@xxxxxxxxxxxxxx>]

Hello Cobalt Users,

It would be great if someone could help me in a mail setup configuration. 
All the examples I found in the web and the HOWTO's are not covering my case.


Here is my configuration:

Qube3 with private address space 192.168.10.99 and registered domain.
qube3.teamstrebel.ch

My Network is connected to via a DSL router to my provider: mypovider.ch
He hosts a SMPT Server with the name mail.myprovider.ch which I use to send 
mail.

My POP server is operated by another provider. He hosts my mailserver with 
the name popmailxxxxx.teamstrebel.ch and has a public IP address.

I can send mail from the home network clients via the Qube3. He is 
forwarding the mail to mail.myprovider.ch

What is not working: when I use Webmail on the Qube3, then I get a error 
message like below:

----- The following addresses had permanent fatal errors -----

(reason: 552 <xxxxxxx@xxxxxxxxxxxxxxxxxxxx> unable to verify address)
----- Transcript of session follows -----
... while talking to mail.myprovider.ch.:
>>> MAIL From:<xxxxxx@xxxxxxxxxxxxxxxxxxxx> SIZE=247
<<< 552 <xxxxxx@xxxxxxxxxxxxxxxxxxxx> unable to verify address

Reporting-MTA: dns; qube3.teamstrebel.ch
Arrival-Date: Wed, 20 Mar 2002 12:17:38 +0100

Q:
What type of DNS records do I have to set up?


Thank you in advance

Jakob Strebel
