John Paul,

        The possibilities are many, but the most likely are as such..
1) The previous owner of your IPs (not knowing how long you've had these
IPs), did some naughty things with them and got those IPs blacklisted.. I'd
contact your ISP and just get a different block of IPs if this is the case.
2) They have a legitimate concern about your IP block, do you have a mail
server running on your network? Are you absolutely certain it is not an
open relay or has a hole that allows open relays? Abuse.net has a excellent
tool for checking this. http://www.abuse.net/relay.html If you did have an
open relay, repairing it should raise your grace in the eyes of the
blacklist operator.
3) Looking at the URL provided.. It looks like they're not a list of open
proxies or relays.. They seem to be just keeping track of dialups and
broadband IPs to reduce the amount of spam coming from those addresses since
many spammers use them to email spam using their own mail server instead of
using their ISP's mail server to attempt to circumvent their ISP's anti-spam
policies. They provide an email address on their website and instructions
for removal. It seems pretty simple to me.

Subject: PDL anti-spam blacklist

First off, I am not a spammer, nor do I sympathize with spammers or spam. I
am not dial up, nor dynamic IP'd, yet on their blacklist.

I take Internet security very seriously.

My personal IP range is blacklisted by these guys for some reason. Looks
like the PDL is somehow "enforcing" my ISP's TOS and/or AUP, go figure...

#1 Has anyone else run into this "service"?
#2 Has anyone successfully had themselves removed from the list? If so, was
the process like bad dental work?

http://www.pan-am.ca/pdl/

Please understand I have not taken the time to verify the entire list as
dial-up vs. not dial-up, I have better things to do than check the PDL's
work.

This is not intended to be the start of yet another un-ending philosophical
debate on spam blockage.

Thanks,

John
