Yes, that description fits quite well.

The filter is at 
<http://whatever.frukt.org/mimedefangfilter.text.shtml> if you 
want more details.

It does some more stuff as well in filter relay. Some hosts are 
exempted from the grey lists based on host names, and some are 
rejected based on previous behaviour with two dynamic black lists.

60 days currently.
