Did you check the reputation of your /24 neighborhood?
I have seen Microsoft blocking entire /24 neighborhoods on the basis of a single IP sending spam.
You were probably hit by that as collateral damage.
- ryan-c 9y agoYes, I did. It was clean as far as I could tell. It was not just Microsoft, I also had issues with Yahoo, AOL and some others. The block I'm in is listed in some RBL called "spamgrouper"[1] but as far as I can tell nobody pays attention to it. No other lists showed any trouble. 1. http://www.spamgrouper.to/ http://www.spamgrouper.to/
