AOL Postmaster blog
AOL announced today they are launching a postmaster blog http://journals.aol.com/pmtjournal/blog/
I’ll be updating the blogroll, too. I’ve been checking out some new delivery / marketing blogs the last few weeks.

Yahoo, part 5…
… wherein I rename this blog “What change did Yahoo make today.” No, really, I like the guys at Yahoo a lot, but really, occasionally I would like to blog about something different!
Today’s change, actually yesterday’s, is that Yahoo has closed their beta FBL program to changes or additions. It is a beta program, this is not unexpected. They will be making changes based on the results of that program and will open it up sometime in the future.

Yahoo delays, part 2
A number of people have posted to various mailing lists and made blog posts pointing to the Yahoo Mail blog post discussing recent problems Yahoo was having with mail. The general feeling seemed to be “AHA! That’s what is wrong!”
Unlike many of my peers, I do not think this explains the delivery problems senders have been seeing while attempting to deliver mail to Yahoo. The Yahoo mail blog article is talking about the Yahoo outgoing mailservers (smarthosts) for their non-webmail users. It is extremely unlikely that these are the same servers used for incoming email.
While I sympathize with everyone who had the AHA! moment and thought their delivery problems were being acknowledged and addressed by Yahoo! I do not think this is really what that blog post is saying.
I am hearing from people that Yahoo is aware of a problem with delayed incoming email, and they are working on fixing it. This does seem to be a broader problem than just bulk mailers, I am hearing from small and mid-size ISPs that they are having significant problems delivering email to Yahoo, too.
For more information about what Yahoo is doing to filter mail check out my previous post Greylisting: that which Yahoo! does not do.
Unauthenticated email
A few weeks ago, NetworkWorld posted an interview with Mark Risher of Yahoo. In it, Mark talked about how Yahoo had no plans to outright block or refuse any unauthenticated email. Of course authentication will be a large part of their decision making for incoming emails but they cannot just refuse to accept mail that is unauthenticated, because there are times when unauthenticated email is the most important mail to their recipients.
A lot of marketers often seem to forget that they are competing for time and space with other, non-marketing, types of email. Email from friends and family and discussion lists are both more important to most people that the latest and greatest email advertisement. These are the emails people want to receive, the ones they open, read and respond to.
In terms of authentication, right now the majority of wanted emails are unsigned with DK or DKIM. Sure there are the early adopters who are using DK/DKIM to sign their emails, and a few large ISPs have started signing outgoing email. But until the vast majority of wanted email is actually signed, recipient ISPs are going to have to accept unsigned email.
Looking forward, even if all of the ISPs sign email sent through their SMTP servers, there will still be some fraction of desired email that will be unsigned. Individuals and small businesses who choose to run their own mailservers may not sign email. Even though these servers make up a tiny fraction of total email, they make up a much larger fraction of wanted email. ISPs cannot block this email without angering their customer base.
Marketers should not be concerned about ISPs blocking unauthenticated email, as it is extremely unlikely that any major ISP will do that. Marketers should focus, instead on making their email relevant and wanted by the recipients. I have been recommending clients plan to have all their outgoing emails DK/DKIM signed by the end of 2008.
