I don’t think there is a standard for naming the domain name. Technically it’s not necessary, because the relevant information is saved in the DNS records (i.e., _xmpp-client._tcp
and _xmpp-server._tcp
), so it’s only a usability question.
I think it makes more sense to use [email protected]
for both, your JID and your email address. That way you, you only need to tell your people one address (and they only have to remember one) and mention that they can reach you via XMPP and/or email.
On the Web, you can specify which channel to use, by linking to the full URIs, e.g.,
<a href="xmpp:[email protected]">…</a>
<a href="mailto:[email protected]">…</a>
Of course people might still confuse it (especially those that consider anything with a @
to be an email address), but thanks to offering both channels under the same address, their message will not be lost.
