Dear all,

Since a few days i have hired my first VPS. This is a test VPS.

It works like a charm!

But I also want to test with email to send to exchange
I have added 1 domain in DA.
I have "unchecked" the local mail server under the MX records section.
I have removed the mail A record with the IP of the VPS and i have added a mail A record to the exchange server.

When i have the "basic" settings, i can send and receive email with roundcube.
After i change the mx records, i get the 550 authentication required error and a bounce.

What happens:
If i send from the exchange: i can send the mail to a hotmail account.
If i reply on the email from hotmail, then i get a email back with the error 550.

I have searched in a lot of topics and the internet, but i'm stuck at this point.

Please advice.
 
Because this is a exchange server, I think you need to add a SRV record in DirectAdmin DNS management. Here is a example of how it should look like, but you need to change it to be your exchange server address:

Code: 
_autodiscover._tcp	SRV	1 100 443 autodiscover.domain.com.

After you have changed the above and added it to DNS in DirectAdmin, you can test the connection here: https://www.testexchangeconnectivity.com/
 
Hi Ditto,

Thanks for your quick answer!

That one is new for me, but it doesn't work, still got the same order; 550....

I never had this settings (SRV) does it mather that it's a SBS 2003?
 
Unfortunately I don't know much about exchange servers. What I posted was only based on one of my customers, wich needed this SRV. But it might not be needed for you.

Does your domain name give any errors at http://intodns.com and http://mxtoolbox.com ?
 
You shouldn't be able to use Roundcube on your server with a domain whose email is NOT hosted on your server.

Roundcube is designed for local email, but you've turned off local mail.
