Post Install Can't complete email verification

Support Self-hosting
1

I’ve installed Discourse on a new VPS. But I’m unable to complete verification and login.

I’ve been following along with
Troubleshoot email on a new Discourse install

The problem from what I can see seems to be Discourse not liking the SSL hostname for the mailserver. It’s configured to mail.posklip.co.za. As this is a shared server the server hostname will be different to the mail hostname. Does anyone know what Discourse is expecting when it raises this error? Should I configure Discourse with the main server nam

Some additional things I’ve checked so far

Mail Server Setup
My MailServer is configured and working in production as a shared hosting server. Dkim, SSL and SPF are setup. I’ve also included the new server IP in my SPF setup.

SSL Test (https://ssl-tools.net/mailservers/mail.posklip.co.za)

You need to install correct ssl certificate on your mail server.

The currently install certificate on the server does not have mail.posklip.co.za as it’s alternate name

Easier: just configure your mail server as 20.atservice.co.za instead of mail.posklip.co.za

@RGJ Thanks! That solved the issue.

So for anyone else bumping into this if your mail server is on a Shared hosting server you need to use the hostname of the Shared hosting server and not your domains DNS name for your Mailserver.
