Current *sendmail-8.13* implementation *does not* make "explanation strings" 
passed by cyrus-imap (smmapd) with TEMP or PERM replies available in

It is sendmail's implementation fault but it can be fixed in smmapd by making 
smmapd use differnt reply formats based on map name
* "cyrus" map -> preserve current behavoiur
* "cyrus-ib" (in band) map -> no TEMP/PERM replies
	for ok user return OK:user at domain
	for over quota user retunrn over-quota:user at domain
[It would require small fixes of feayures too ]
