I found four on that list, out of hundreds, and none of them actually 
say any spam was sent.  Two complained our reverse DNS doesn't match. 
They list you for things other than actually generating spam from your 
address, apparently.

Ours is fixed. We really haven't had any problems with our IP.

It says a lot to me, that you can get on spam blacklists without ever 
sending spam, which was a surprise.  I certainly wouldn't want to 
subscribe to a list that's doing that, so I'll be more aware of the 
issue going forward.

Given that I can't mail you while my few dozen users haven't run into 
that problem with anyone else out of our lengthy client list in over a 
year, it seemed to me that your system was set at the "hyper-paranoid" 
end of the sensitivity range and I thought you'd like to know.  If you 
do know and are content for it to be that way, so be it.
