We are not, but I don't understand how that matters, since I'm only 
seeing these bounce messages coming from a handful of the domains 
we host (17).

I know what it is, but we as of yet do not run it because it is:

backup MX aware of all the users, but I don't know how or if the 
qmail patch supports anything like this, and I've also heard that 
it can be done with LDAP, but having never set up LDAP, that seems 
overly complex, and sounds like it would rely on some LDAP server 
being up which would defeat the purpose (our backup MX is at a 
geographically distant location, and is intended to be able to run 
fine in the event of all our other machines going down).

Ideas?  Further knowledge?
