Just tragic, isn't it?

;-)

Actually, that issue hasn't been too much a problem for me.  Responsible 
postmasters are usually pretty quick to fix errors like that, even in 
the edu domains.

Bigger problem are legitimate collaborators who can't figure out how to 
get their systems patched and/or un-blacklisted.  Those are the folks 
who prevent me from using rbl lists.
