Setting up DNS for domain & subdomain and MX records for both (using separate servers)

Product Support

AI-generated summary

Solari sought help with setting up DNS records for a subdomain (discuss.whatitis.com) and mail handling, separate from the main domain (whatitis.com). The main domain hosts a Wordpress blog on one server, while the subdomain hosts a Discourse forum on another server. IAmGav advised setting up a subdomain and an A record pointing to the Discourse forum. After receiving confirmation, Solari successfully set up the configuration, which involved dealing with multiple MX entries and setting up additional SPF/DKIM records.

I’ve read and read up on this but I am still a little confused on the proper setting up of DNS records for subdomains and mail handling for Discourse.

Let’s say I have a domain whatitis.com:

  1. I have a Wordpress blog on a separate server at whatitis.com

  2. whatitis.com has its own MX record/email on the above server.

  3. I want to put discourse on discuss.whatitis.com on its own server.

  4. I want discourse emails to be on the discuss.whatitis.com subdomain.

I’m confused as to whether to set up CNAME or A for the subdomain too, etc. etc.

What’s the recommended format for this sort of thing? I host my DNS on VULTR at the moment and their interface is relatively easy, I’m just clueless as to the proper settings for the above setup, that’s all. ; )

Many thanks.

You will have to setup a sub domain for the discuss.domain.

Then when that is done, set an A record to point to the discourse forum.

Thanks for the confirmation – I got it working. Was a bit tricky with more than one MX entry and needing to set up additional SPF/DKIMs and all that. ; )

Thanks!
