AOL has disabled the IP reputation check and the rDNS lookup on their postmaster pages. Given AOL isn’t handling the first mail hop any longer, this makes perfect sense. They simply don’t have the kind of data they did when they were handling mail directly from the sender MTA. There’s no information, yet, on whether […]
The Yahoo bounce problem has been resolved. There were erroneous ‘554: this user does not have a yahoo.com account’ between March 14 and March 16. If you attempted to send mail and received this bounce during that time you can reactivate the address in your database. Most ESPs should be able to help you with […]
I still don’t have any solid information on the cause of the Yahoo bounces. I do know that folks inside Yahoo are looking into the issue. However, multiple people (including my clients) are reporting that the addresses that are bouncing have very recent click and open activity. Other reports say these addresses deliver on a […]
Multiple folks are mentioning seeing an increase in “user unknown” responses from Yahoo. Some people are discussing this with Yahoo. Right now, best advice is to believe these are accurate user unknowns. UPDATE: There is increasing evidence these are not valid user unknowns. See next post.
AOL posted on their blog today about changes to DMARC reporting and FBL messages as they continue to transition domains to the OATH infrastructure. As AOL domains go to the new infrastructure, DMARC reports for those domains will be included in the existing Yahoo DMARC reports. After the MX migration is done, they’ll start migrating […]
Last week some folks were mentioning a spike in unsubscribes from Yahoo. This is being investigated.
The AOL postmaster team posted some information about the upcoming MX transition on their blog. [S]tarting this week, the majority of AOL’s MX records will point to [OATH’s] new combined servers. This should be transparent to any sender as those servers will operate in simple pass-through mode. This means senders with established FBLs will continue […]
We’ve known for a while that AOL email infrastructure is going to be merging with Yahoo’s, but apparently it’s happening sooner than anyone expected. The MXes for aol.com will be migrated to Yahoo infrastructure around February 1st. Reading between the lines I expect that this isn’t a flag day, and much of the rest of […]
This is the time of year when everyone starts posting their predictions for the coming year. Despite over a decade of blogging and close to 2500 blog posts, I have’t consistently written prediction articles here. Many years I don’t see big changes on the horizon, so there’s not a lot to comment on. Incremental changes […]
A number of people have mentioned over the last couple weeks that they’re seeing a spike in Yahoo rejecting mail with 554 delivery error: dd Requested mail action aborted Discussions on various mailing lists indicate these messages are related to inactive accounts. Addresses that bounce at Yahoo with these codes should be handled as inactive […]
