Standard xmpp addresses

What is the standard xmpp addresses?

username@im.domain-name.com

username@jabber.domain-name.com

username@xmpp.domain-name.com

What are people or companies general using?

Many are using “jabber”, but the others are also in use. However, you should take username@domain-name.com, if possible.

I preferred username@domain-name.com too. being consistant with email addresses. But the problem we have our mail is on different server then our openfire server. Plus other users uses external mail servers.

With this situation, how can we use username@domain-name.com? Also we can’t wait for the multi-domain feature that has the hight vote for implementation.

We currently use username@im.domain.tld for our employees. We started out with username@domain.tld but had to change because of complications with server-to-server communication issues with a 2nd Openfire server we have.
