The problem is your provider probably hosts spamming customers so their IP ranges end up in black lists. Spam Haus is a good example of these services that track spam based on IP addresses. Also note if you run your own SMTP mail server on mobile IP space or space that's known and recorded with ARIN as remote access ranges you'll automatically be included in some blacklists. Not everyone uses these services but many companies use comercial antispam solutions that grab a lot of this data to build their rules sets. I'm absolutely certain from the several messages on this thread that I've seen so far that your experiencing some variation on this theme.
