It's a feature of CanIt and CanIt-PRO, our commercial solutions. It would
be quite easy to add to MIMEDefang, but obviously we need some incentive
to lure people into CanIt/CanIt-PRO. :-)
The idea has been extended by the "greylisting" folks at
http://projects.puremagic.com/greylisting/ (Unfortunately, URL appears
to be dead right now.) CanIt and CanIt-PRO in CVS now feature the
full greylisting technique.
Regards,
David.
