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.
We’ve known for a while that AOL email infrastructure is going to be merging with Yahoo’s, but apparently it’s happening sooner than anyone expected.
The MXes for aol.com will be migrated to Yahoo infrastructure around February 1st. Reading between the lines I expect that this isn’t a flag day, and much of the rest of the AOL email infrastructure will be in use for a while yet, but primary delivery decisions will be made on Yahoo infrastructure.
The AOL and Yahoo postmaster teams are pretty smart so I assume they’ll have made sure that their reputation data is consistent, and be doing everything else they can do to make the migration as painless as possible. But it’s a major change affecting a lot of email, and I wouldn’t be surprised to see some bumpiness.
If you’ve done anything … unwise … with delivery to AOL addresses, such as hard-wiring MXes for delivery to aol.com, you should probably look at undoing that in the next week or so. I’m guessing the changeover will happen at the DNS level, so if you’ve nailed down delivery IPs for aol.com you might end up trying – and probably failing – to deliver to the old AOL infrastructure.
AOL posted on their blog today about changes to DMARC reporting and FBL messages as they continue to transition domains to the OATH infrastructure. As AOL domains go to the new infrastructure, DMARC reports for those domains will be included in the existing Yahoo DMARC reports.
After the MX migration is done, they’ll start migrating the actual user mailboxes. Right now, FBL messages for AOL properties are coming from AOL and will continue to do so until the actual mailbox is transitioned to the new infrastructure. Once the mailbox is transitioned, then any FBL emails from that address will come from the Yahoo infrastructure. The blog post at AOL suggests signing up for both AOL and Yahoo FBLs during this transition phase.
It does bring up an interesting question as to whether or not the combined FBL is going to be IP based, DKIM based or a mix of both. It sounds like at least during some part of the consolidation there will be a DKIM only FBL. It could be that there will be some expansion to an IP system in the future. Or, it could be that all FBLs from AOL addresses will be based on DKIM domain.
And, in fact, they are.
This time I’m seeing random reports of FBL failures. Some folks are seeing a significant (more than 50%) decrease in FBL emails. Other folks are reporting FBL reports that aren’t really FBL reports, but instead look like failed code output.
If you’re seeing this kind of problems it’s not just you.
As always, people at AOL are working to fix things and cooperating with people in the sending community who are having this problem. In other news, I found out last week that the one Really Smart Mail Guys I thought was still there is still at AOL but is no longer in their mail division. That means that the guys who built the AOL version of Skynet have left it to its own devices. Be afraid. Be Very Afraid.
