Bootstrapping email setup: subdomain necessary?

Hi there! I’m a complete novice at sysadmin stuff. I had a question about the following quote from the Bootstrapping tutorial:

Please note that in any email provider, you must verify and use the subdomain, e.g. . If you verify the domain only, e.g. , mail will not be configured correctly.

Does this apply even if, in Digitalocean, you’re using a domain ( for your droplet, and not a subdomain? Thank you


A subdomain isn’t necessary as long as your mail domain and Discourse domain are the same.

E.g. if you’re hosting Discourse on and your mail server sends from there shouldn’t be any issue.
