First: Many thanks for this great addon here. The team are amazing
My Setup works fine, all green
But now i will create a new external Domain for a User. (same with mailgun service)
The user login works fine.
I send a mail with the new domain and it works, without any changes.
But i can not answer. I write a mail on gmail, with no errors. But the mail not received
Its the same function which you use on mailgun software. Buy a domain, and make the dns records.
Many thanks alento. I dont know how i can write a pm here, but no problem.
Hostname: extrem16.services
For testing, i buyed a test domain with namecheap. firma-saalfeld.de (no changes)
Then i added this domain to a user.
Then i go to roundcoupe and write a mail to gmail. That works!
But now i will answere with gmail, and this mail is not received.
If i use my hostname mail for checking, then both works
You seemingly have chosen to use External DNS for firma-saalfeld.de but have not entered any of the necessary records into your DNS providers panel. Your DNS is being handled by dns1.registrar-servers.com and dns2.registrar-servers.com (Namecheap)?
You need to either point the name servers to ns1.extrem16.services and ns2.extrem16.services or add the entries from the External DNS area of the admin pages to Namecheapโs DNS. I suspect that you will need to do the latter as .de is (I believe) one of the TLDโs that strictly enforces more than 1 IP address for name servers. You may want to consider setting up Secondary DNS with puck.nether.net/dns to remedy this limitation (if it exists).
