AOL FBL petering out
This is pretty clear evidence that AOL accounts are being transferred to the Oath / Verizon Media / Yahoo backend.
AOL has been slowly disabling their postmaster pages and I don’t trust them to provide accurate info any longer. I am also way of using the contact forms at AOL these days. It’s possible that no one is monitoring them.
Looks like the last of the AOL mail infrastructure is nearly gone.
