I’ve done a new install of HestiaCP on a new install of Ubuntu 18.0.4 LTS and all was ok until I tried mail-tester.com, which complained my hostname didn’t match so I used v-change-sys-hostname to mail.domain.tld.
However, after doing that going to mail.domain.tld/webmail or mail.domain.tld/phpmyadmin no longer works. Also tried domain.tld/webmail and the original hostname, but only get page not found.
I suspect this is a rookie error, because this is my first install of HestiaCP. Any guesses as to how I’ve screwed this up or what I’ve missed?
Ancillary question: Once you have more than one website on a server, so potentially many domains, how do you handle the HELO mail sending the right domain (or does it always use the hostname regardless of the email domain sending from?)
