AOL has discontinued their blogging platform. This means the AOL postmaster blog is no longer active. I suspect the AOL postmaster team is exploring their options and trying to find a way to continue blogging.
If I hear anything one way or another, I will post it here.
AOL assures me they are migrating to a new platform and the blog will be back up.
I also managed to grab a copy of the IP Reputation post that AOL put up and I linked to last week.
