Weird spate of AOL and Yahoo 'undeliverable' bounces
We sent a message out to our alumni mailing list and got a whole bunch of bounces like this:
The attached message was received as a bounce, but either the bounce format was not recognized, or no member addresses could be extracted from it. This mailing list has been configured to send all unrecognized bounce messages to the list administrator(s).

I'm afraid I wasn't able to deliver the following message. This is a permanent error; I've given up. Sorry it didn't work out.
Subject: [Alumni] REMINDER: Join Us | APhA Annual Meeting & Exposition Alumni and Friends Reception
Complete with the weird background color
Strangely EACH and every one of them was a yahoo or AOL address (Yahoo now owns AOL)
Could they be bouncing this based on SPF, DMARC or DKIM issues and just not telling us?

Interesting. Coincidently, earlier today I received a more or less identical Failure Notice for a message to an address @aol.com. According to my mail log, the message was accepted by mx-aol.mail.gm0.yahoodns.net and then subsequently the Failure Notice from aol was returned.
However, I just now tried sending to the same aol.com address and this time mx-aol.mail.gm0.yahoodns.net rejected the message with 552 1 Requested mail action aborted, mailbox not found (in reply to end of DATA command)

For a few months I have received rejections for @aol.com addresses fro0m a non-Mailman list I manage:

Subject: <redacted> To: xxxxx@aol.com
In many cases, when I resend the mail a few days later, I get no rejection. This error message gives NO information as to why the was not delivered.
