Hi guys, I opened this thread because I had a huge unusual TS03 block in yahoo this weekend. I have been mailing consistently for quite some time, and I usually get this blocks based on volume sent, but this time I had blocks for IPs that sent very little. The block came spread across multiple providers and networks, it seems arbitrary. :dontknow: I dont see a spike in bounces or complaints. Anyone seeing something like this? Holidays seem to be driving everyone mad!
