Ah, the plot thickens.

A good solution here would be a private protocol extension between
the different hosts that provide part of the service. Always good
when you don't have to upgrade the entire internet to solve the
problem at hand.  :-)

We already use this trick in a couple of places. But it only works when the
components all come from the same vendor. In many cases they don't. For
example, we often see our IMAP server used with someone else's webmail
interface.
