Mail Server FQDN?

[Ovidiu]

The docs say:

5. Make sure server hostname is FQDN compliant

and show an example of:

root@localhost:~# hostname
localhost
root@localhost:~# v-change-sys-hostname mail.vestacp.com
root@localhost:~# hostname
mail.vestacp.com

am I safe with this:

Code: Select all

root@hosting:~# hostname
hosting
root@hosting:~# hostname -f
hosting.knightsenglish.com

Then it says:

8. Enable DKIM support.
This is optional step but highly recommended. DKIM can be enabled in the Vesta under MAIL tab.

So, I'd like to use VestaCP for DKIM but not for DNS. So where can I see the DKIM keys so I can set them up on my own DNS?
