We're seeing an increase in the amount of mail we're bouncing to @*.rr.com addresses with the following diags:
smtp;550 5.1.0 <envelope.from> sender rejected AUP#I-1310 smtp;550 5.1.0 <envelope.from> sender rejected AUP#I-1320 [image: Inline image 2] I've not seen any other posts in mailop about this, but there are a handful of posts on TWC's forum. I'm also not seeing this diag listed on their Postmaster pages. All my searching is pointing toward a problem with TWC. Does anyone have any insight? Anyone else experiencing the same uptick in volume over the past 20 days or so? Justin
