Looks like you have got yourself on to some blacklists, check you arent an open relay or spam source.

Then once you have done this go to each of the sites and ask for your IP to be removed.

We had similar situation on this day. Turns out that our server was using the blacklist site of "ORDB.ORG", which has been out of business for awhile. I removed it, and all worked well.
