Dead email domain:

A representative of Facebook confirmed for me that the email service handling mail for email addresses is no more. PC Mag had previously shared that FB was warning users back in April that this was coming.

Thus, it is now safe to block, reject, unsubscribe or otherwise filter out all mail to the domain. I have no clue what they'll do with it in the future, but if it was me, I'd let it bounce for a while, then turn it into a spam trap domain, feeding spam filters or blacklists. If they have the same idea, you'll definitely want to stay away.

Do you need COI/DOI? Probably.

In case you've been living under a rock, or you've been lucky enough to not be affected, here's the deal: Some bad guys, probably Russian or Eastern European, have decided to mail-bomb unsuspecting folks by signing them up for many hundreds or thousands of mailing lists. The bad guys built a tool that either searches for or has a list of signup forms at many hundreds or thousands of websites. The bad guys then submit many email addresses to those forms.

The net result is, if you're on the wrong end of this attack, your mailbox gets filled up with a bajillion newsletters. Some from big brands. Some from small brands. Some from companies you've heard of. Some from non-profits you've never heard of.

Yahoo: Deferring Inbound Connections Today

Since about 6:00 am eastern this morning, Thursday, August 25, Yahoo has been deferring delivery attempts from almost everyone ESP or mail platform I'm hearing from. My guess is that there's a spam filter update issue or system capacity issue over at Yahoo. As far as we can see, almost all inbound mail is affected. Inbound connections are timing out, or giving unexpected TS01 errors, or giving "temporarily deferred" errors.

Stay tuned, I'm sure the good folks at Yahoo are on it and will address the issue as soon as possible.

Where do I get a new IP address?

Someone asked me the other day, where can they get a new IP address? Their current IP address is "blacklisted" at Yahoo and Hotmail, I was told. It's easy enough to get a new domain name, but what about the IP address?

They let me know that their deliverability was suffering and that getting this fixed was very important to them.

I had to ask, though, why do they think the new IP address wouldn't have deliverability issues? Deliverability issues are reactive. Something has to have happened to make the ISP take a dim view of your mail, of your IP address. You don't just get blacklisted because your IP address contains a "7" in it. Something has to change in your sending or list hygiene practices. Are you engaging in email append? Are you buying lists? Are you sending to very old data?

Until you figure out what's causing the "blacklisting" and actually fix that, don't expect a new IP address to just magically fix everything. What will happen is, you'll try to warm that IP address up, it'll seem to go okay for perhaps a few weeks, but then you'll start to see the same issues on the new IP address that you saw on the old IP address.

It's kind of like changing your shirt because it's got blood on it. If you've got a bloody wound, changing your shirt doesn't actually close the wound.
