That's assuming we've heard both sides of the story.. truthfully. I've been in Damien's shoes - resellers that don't care who they sell to as long as a buck is made, massive amounts of spam, etc. At the end of the day, it's not his job to worry about the clients of clients of clients of clients. His job is to worry about *his* company, and to avoid CC-style SBLs that would affect *his* clients. He shouldn't have to 'work something out' with someone that's blasting such a ridiculous amount of spam, especially if warnings were already issued.
I'm more curious as to how many clients up and walked out. Not because of the IP issue, but before that: when they suddenly found they couldn't send their legitimate emails due to sharing a net range with spam blasters.
You raise several good points.
I am not using my BitAccel VPS for email, so I would not have noticed any blacklisting if it had occurred.
Whatever happened with the IP address blacklisting problems (or any other similar issue), the proper approach would have been for Damien to provide escalating warnings to Corey, explaining the problems, the expected corrections, and the consequences if the problems were not corrected. It would be improper for Damien to deallocate the IP addresses on short notice without warning.
As an end customer, I am not privy to the communications that went on between Damien and Corey. Corey asserts that Damien did not give any warning before announcing the deallocation of the IP addresses. Damien has not denied it. That does not prove that Corey is right, but it lends credence to Corey's telling of the events (along with the other supporting information provided by Corey in this thread).
Did Corey mess up by not having a signed contract and possibly failing to manage spammers? Absolutely.
Is Damien culpable for deallocating the IP addresses on ridiculously short notice, callously disregarding the impact that it had on innocent bystanders like me? Absolutely.
The difference? Corey made mistakes. Damien acted with deliberate intent and malevolence.
