Hey #xmpp and #jabber experts on Mastodon: my XMPP server is im.interfree.ca, and so my JID is fastfinge@im.interfree.ca. However, I would like to alias my JID to fastfinge@interfree.ca. That way my email, jabber, and fediverse id's are all the same. I control the DNS on the entire domain. How can I do this? A quick search isn't finding me a list of clear and straightforward steps.
@fastfinge As others already pointed out, you can do it with SRV records. As a bit of expectation management, be aware that XMPP is stricter with routing so there isn't really the kind of aliasing you may be familiar with from email. If you already have contacts with that JID then those will stop working if you rename your host.
