yesterday we created a zone called men.at.
Because we have a webserver running and want to reach the webserver with the same url from inside and outside. this was working.
But then we saw problems with the mail server. when we type nslookup and our mailserver , an error comes up. because the mail server is mail.me.at , just an example.

We created an A record for mail.men.at and nslookup is working.

But now the office2 cannot send emails to our office1.

Why ?

Ok guys, after some time and waiting all emails arrived.
The problem was the new created zone men.at.

But how can I get rid of this problem ?

You know, we have a webserver running in office1 inside the domain men.at.
The domain should be reachable from inside and outside with its https//....... address.

Therefore we created a primary zone in office2 called men.at. But you know afterwards all email from office2 to office1 cannot be delivered.

What is to do, when I create a zone which is also my partner domain and I have to sent eamil to them ? What do I have to do ?

Yes office1 and office2 are connected over site2site vpn.
We have diffenerent domains. but this is ok.

office1 has men.at
office2 has pdv.pt

So, when I enter a prim zone to office2 called men.at , what do I have to enter more ?
