The this is the domain portion of the JID is a host, and is what pidgin
uses to look up what ip/machine to connect to by default.

If, for whatever reason, that domain name does *not* resolve (via DNS) to
the correct host then DNS SRV records should be set up for pidgin to use
to resolve the correct host.

If the domain is not the correct host *and* DNS SRV records are not
available for the domain then pidgin allows you to manually specify a
connect server to override the DNS lookup on domain.

I am still not at all capable of really asserting what the 'correct'
behaviour here is with respect to the connect server/DNS resolution, but I
*think* using the given domain is in fact correct and that the recently
created XEP-0233 is designed to answer exactly this situation.

I will attempt to bring this up in one of the XMPP chat rooms when I am
next able to spend some time discussing it with the people who might know
