Sticky Post: Please Hire Mike Teixeira!

My esteemed industry colleague Michael Teixeira is looking for an opportunity in the anti-abuse or email fields. Got something suitable that you’d like to interview him for? I hope you'll consider him. He and I have something in common – we’ve both worked spam issues for MAPS (Mail Abuse Prevention System-- the first anti-spam blacklist group) – me, for a time before Trend Micro acquired MAPS, and Mike, after.

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:"

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.

Vodafone Ireland: is a dead email domain

Even though the Vodafone Ireland domain has six active MX records, this appears to be a dead email domain, and I suggest you suppress all 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 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.

Reference: Apple email domains

What are Apple's email domains, in case you were wondering? For end consumers, customers who have registered for Apple IDs and/or email accounts, those domains are:


Apple saysIf you created an iCloud account on or after September 19, 2012, your email address ends with If you created an iCloud account before September 19, 2012, or moved to iCloud with an active MobileMe account before August 1, 2012, you have both and email addresses. If you had a working email address as of July 9, 2008, kept your MobileMe account active, and moved to iCloud before August 1, 2012, you can use,, and email addresses with your iCloud account.

For corporate email, Apple's email domain in They don't appear to use localized email domains like or They do use sub-domains under (like for various services, including email. But they have a wildcard MX record for all sub-domains, so it's not easy to tell what's valid or not. That might mean they accept misdirected mail to sub-domains and use it to feed their spam filtering (spamtraps).
