Defeats the purpose of self-configuration, UNLESS the mailstore provider 
can automatically provide it.  See my posting under "We don't need no 
stinking..." for a method to do it with TXT records.

We don't want to modify _anything_ in the mail stream if we can possibly 
avoid it.  If we do, sites can't do this without infrastructure changes 
(which may never happen in some environments).  Eg: if Microsoft elects 
not to follow this spec, we've just disenfranchised Exchange environments.

Having it purely in the UA, and perhaps DNS for signalling, make it a 
_lot_ easier to deploy.
