They denied any knowledge of three /29s being listed or having any involvement in it happening. They said they have a spamhaus license, which I'm assuming is for their own servers, and that they would leverage that to ask a support question, but they're disclaiming any responsibility. These aren't new netblocks for us from them, but it seems awfully weird that we would be operating on these IPs for 2+ years then all of the sudden have them listed like they're dialup IPs. The message I received during the delisting process with spamhaus/PBL for "MyProvider" was: Outbound Email policy of MyProvider LLC for this IP range It is the policy of MyProvider LLC that unauthenticated email sent from this IP address should be sent out only via the designated outbound mail server allocated to MyProvider LLC customers. To find the hostname of the correct mail server to use, customers should consult the original signup documentation or contact MyProvider LLC Technical Support. I don't know if that's just a boilerplate message or it actually refers to the precise reason why my IPs were added to the PBL.
