Yeah that sucks. But you have to admit their reasoning is pretty sound.
The minimum "credible" IP suitable for duty as an email server is probably a cheap VPS somewhere.

Getting off the lists is an enormous pain in the ass. They make absurd demands, like changing the rDNS on every single IP in the block to contain the word static.... as though breaking rDNS is a good idea.
That "static" thing is just stupid. God I wish ISPs would just standardise on putting "dyn" into the rDNS of their dynamic IPs though. That would solve so many problems.
That's exactly what happened. It was apparently dial-up space many years ago.
I say many, because the space in question has been under my control since 2005, and it's STILL on the dynamic ip list, despite a roughly annual attempt to get de-listed.
