Spam Cannibal blocking list is dead
Multiple folks reached out to me overnight to let me know that the SpamCannibal DNSBL has blown up, that they have effectively "listed the world," resulting in mail admins blocking all mail if they use this DNSBL in their mail server configuration. I talked to the operator of the list, who let me know that Spam Cannibal is permanently shut down and that the domain must have expired. More over on DNSBL.com.

Spam recall: For real!
Remember how Outlook had that horrible "Recall" function that didn't work because anybody with a brain could just force quit Outlook to prevent it from deleting the original message? This has nothing to do with that. If you still use Outlook (I don't) and if that feature still exists (I have no idea), don't use it. When observed, it is a strong indicator that the person hitting the recall button doesn't know how real SMTP email works.
Anyway...
There is an honest-to-god real SPAM recall at the moment. The USDA is recalling 228,000 pounds of Hormel's deliciously salty and fatty good stuff because there may be metal bits embedded in the meat. Here's more info. I need to go check my cupboard; I usually keep a can on hand because it does well when you fry it up with eggs in a pinch as a sort of substitute bacon.

Whoops! Cyberlogic DNSBL Broken
Looks like the anti-spam blacklist at dnsbl.cyberlogic.net has listed the entire world. More info can be found here.
AOL: No More Whitelisting
As AOL and Yahoo continue their transition into one platform, things were bound to change over time. As a result of this ongoing consolidation, AOL no longer offers whitelisting of sending IP addresses. Though the form still seems to be up at the moment, any submissions seem to get a reply from the AOL Postmaster robot saying, "Whitelisting is no longer offered or needed for mailing to AOL. If you see delivery issues please sign up for a Feed Back Loop at: https://postmaster.aol.com/fbl-request"
As the net effect here is that AOL seems to be moving onto Yahoo's platform -- if you're wondering how to troubleshoot AOL delivery issues today, the general deliverability guidance for Yahoo is probably your best place to start.
For now, it seems as though the AOL Feedback Loop is still in effect. I do suggest registering for it as long as it is still possible, but also, be sure to sign all mail with DKIM and register with the Yahoo FBL as well, so AOL users are covered on both sides of the possible feedback loop equation.

Unroll.me to close to EU users
As mentioned on Slashdot, TechCrunch is reporting that unsubscription service Unroll.me is saying that EU users are no longer welcome, claiming that it's not possible to comply with GDPR.
Vodafone Ireland: vodafone.ie is a dead email domain
Even though the Vodafone Ireland domain vodafone.ie has six active MX records, this appears to be a dead email domain, and I suggest you suppress all vodafone.ie addresses from any email lists.
Vodafone appears to have announced this closure in 2014. The original announcement no longer appears to be online (nor in the Internet Archive), but here's a discussion forum thread on the topic. Based on this information, it appears that email service for the vodafone.ie domain ceased on October 18, 2014.
None of the six MX servers is responding to connections after repeated testing.
Vodafone New Zealand similarly shut down their email service in 2017.
