[Operators] XMPP forwarding and redirect?

[Daniel Pocock]

I'm just wondering about practical forwarding and/or redirection options
for people who want to offer some kind of XMPP service on their domain
but don't really want to run a full service themselves.

For example, many free software projects (Debian, Fedora) offer their
developers mail forwarding (pocock at debian.org->daniel at pocock.com.au)
without having any mailboxes.  Is it feasible to construct similarly low
key solutions with XMPP?
