A few days ago I posted about Yahoo using the Spamhaus lists. In the comments of that post there have been multiple reports of mail being bounced from Yahoo with a reason of “on the PBL” but the IP was not on the PBL.
I am happy to look into this for people. I’m sure neither Spamhaus nor Yahoo want to be incorrectly rejecting email. To do this, though, I need the rejection message from Yahoo, the IP the mail was sent from and when it happened. Feel free to email the information to laura at wordtothewise.com.
