Scott,

Most of the questionable listings that are in there are from the original
IPswitch list (the yourname.usa one may have been mine). I did my best to
sort out as many of the inaccurate ones as I could from the original
IPswitch list, but obviously didn't get all of them. I just purged the list
of the ones you mentioned though, including all of the xxx.net4dnet.com
listings.

By "verify", I mean that I personally, manually added all of the listings
that were not on the original IPswitch list. In other words, I went through
each individual spam myself, and cut and pasted the domain name directly
into the list. It's nowhere near as fast as IPswitch's automated way of
culling addresses, but it's a lot more accurate to be sure. Please do let me
know if you find anything more that is questionable (that goes for everyone
on the list). Like I mentioned, I am pretty conservative myself, and my aim
is to have no false positives, rather than being overzealous.

I've added a few more listings this morning, and minus the ones I just
deleted, there are now 1,867 domains listed. To me, the key to having a good
list is keeping it updated frequently. I probably add at least 5 new domains
to this list each day or so. At first, it didn't make a huge difference to
what was caught, but after awhile it really started adding up.
