I’m seeing a significant amount of chatter on various lists that queues to Comcast are backing up right now. Looks to be something on their end.
Error messages are 421 “Try again later.” I’ll see if I can find someone at Comcast to give me some info.
Over on the DMARC-Discuss list, Comcast announced they had turned on DMARC validation and companies that publish DMARC records should start receiving reports from Comcast.
Read MoreThis morning (9 or 10 am Pacific) my various mailing lists were lighting up with questions about Yahoo delays. A lot of people reported they were seeing Yahoo respond “420 Resources Unavailable, try again later” on connect.
What everyone wanted to know was is if other senders were seeing this.
The answer was a resounding YES.
And, in fact, Yahoo commented on Facebook around 2pm Pacific that they had a mail outage and were trying to bring services back up before close of business today.
As with many things, the Internet rumor mill is one of the fastest and astonishingly accurate sources of information about mail servers falling over.
I started hearing reports that queues were clearing mid-afternoon pacific, but not everyone is seeing that.
So, yes, Yahoo is having a bad day. And it’s not you, it’s not spam, it’s just that some of their mail servers fell over and they’re struggling to accept all the mail headed their way.
It happens.
If you’re interested in hearing more timely updates, I will often announce things like this on twitter when I hear about them.
I updated the Wiki a few weeks ago when I heard, but don’t think I posted anything here. Comcast has changed their delisting form page to http://postmaster.comcast.net/block-removal-request.html. The old form is currently non-functional. You can fill it in, but it’s unconnected to anything on the back end and it won’t result in an IP being delisted from the various Comcast blocklists.
My understanding is that the old form may come back to life at some point, but it’s much safer to use the new form and the new Comcast Postmaster Site.
