Changing the Mail server location from my.* to something else

[BrutalBirdie]

Since version 5.6 it is possible to change the mail server location.

My question, if changing that to something else, like mail.* will I have to reconfigure all cloudron apps?
I know clients and software outside of cloudron for sure but also the cloudron-apps?

Did anyone do that already and can you share your experience?

Cheers

Yes, it will reconfigure the web mail apps that depend on the mail location. The non-web mail apps, are using internal mail container name, so they don't need to be restarted. If you have desktop clients, you have to reconfigure them by hand, of course.

BTW, it will also adjust the DNS as required as long as you use one of the programmatic DNS providers. Otherwise, you have to set this up manually (go to the Status view of each domain after you change the location).

Yes will have to do that since I use namecheap. Thanks for the response.

EDIT:
Will change that later this day and will report the process for future readers.

@BrutalBirdie That would be awesome if you could as I’m hoping to do this at the end of the month. Have my clients a couple weeks notice to update their mail clients if needed.

Update. I have finished my mail server name change.

All the dns records where updated automatically, even the custom MX record on namecheap if it existed before.

The one thing that confused me second was the PTR record aka. reverse dns.

Just went to hetzner and fixed that. All working no problems.

@BrutalBirdie interesting, assume you changed it to smtp.example.com?

from my.* to mail.*

[marcusquinn]

@BrutalBirdie of course, makes sense

@BrutalBirdie Ah good catch on the reverseDNS entry, I'll make a note to change that on my side too when I make the change later this month.

As long as the IP doesn't change from my. to mail. no clients need immediate reconfiguration.

The Reverse DNS is something that I also wanted to change for vanity reasons, but not at the expense of email.

Now I can.
