Whitelisting is dead

A decade or so ago I was offering whitelisting services to clients. It was pretty simple. I’d collect a bunch of information and do an audit on the customer’s sending. They’d get a report back identifying any issues that would limit their chances at acceptance. Then I’d go and fill in the forms on behalf […]

OATH and Microsoft updates

I’ve seen multiple people asking questions about what’s going to happen with the Yahoo and AOL FBLs after the transition to the new Oath infrastructure. The most current information we have says that the AOL FBL (IP based) is going away. This FBL is handled by the AOL infrastructure. As AOL users are moved to […]

What kind of mail do filters target?

All to often we think of filters as a linear scale. There’s blocking on one end, and there’s an inbox on the other. Every email falls somewhere on that line. Makes sense, right? Bad mail is blocked, good mail goes to the inbox. The bulk folder exists for mail that’s not bad enough to block, […]

AOL Postmaster page changes

AOL has disabled the IP reputation check and the rDNS lookup on their postmaster pages. Given AOL isn’t handling the first mail hop any longer, this makes perfect sense. They simply don’t have the kind of data they did when they were handling mail directly from the sender MTA. There’s no information, yet, on whether […]

More on AOL transition to 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 […]

AOL MX Change update

The AOL postmaster team posted some information about the upcoming MX transition on their blog. [S]tarting this week, the majority of AOL’s MX records will point to [OATH’s] new combined servers. This should be transparent to any sender as those servers will operate in simple pass-through mode. This means senders with established FBLs will continue […]

AOL Changes

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 […]

Happy 2018

This is the time of year when everyone starts posting their predictions for the coming year. Despite over a decade of blogging and close to 2500 blog posts, I have’t consistently written prediction articles here. Many years I don’t see big changes on the horizon, so there’s not a lot to comment on. Incremental changes […]

The cut-over date for the mx record for verizon.net to to be handled by AOL is June […]

AOL accidentally hard bounces valid mail

Last night (Mar 29, 2017) between about 8pm Eastern and 9:30pm Eastern AOL suffered a technical issue. Every email sent to them received a “Recipient address rejected” reply.  One example of the error message: Mar 29 20:45:12 p2-lvmail11 lsb1-99-208-250/smtp[22251]: A88DFC2DBE9: to=<redacted@aol.com>, relay=mailin-01.mx.aol.com[64. 12.91.195]:25, delay=0.18, delays=0.01/0/0.14/0.03, dsn=5.1.1, status=bounced (host mailin-01.mx.aol.com[64.12.91. 195] said: 550 5.1.1 <redacted@aol.com>: Recipient address […]
