ISPs speak at M3AAWG

Last week at M3AAWG representatives from AOL, Yahoo, Gmail and Outlook spoke about their anti-spam technologies and what the organizations were looking for in email. This session was question and answers, with the moderator asking the majority of the questions. These answers are paraphrased from my notes or the MAAWG twitter stream from the session. […]

Hotmail having a bad day

Looks like Hotmail / Microsoft is having a rather bad day. Their DNS seems to be intermittent. While they were down a while ago they were returning SERVFAIL for some DNS lookups, including MX lookups. For senders who have the DNS data in their recursive resolvers, this will have no impact. For senders who either […]

“Blocked for Bot-like Behavior”

An ESP asked about this error message from Hotmail and what to do about it. “Bot-like” behaviour usually means the sending server is doing something that bots also do. It’s not always that they’re spamming, often it’s a technical issue. But the technical problems make the sending server look like a bot, so the ISP […]

SNDS is back

For years now, Microsoft has maintained Smart Network Data Services (SNDS) for anyone sending mail to Hotmail/Outlook/Live.com. This is a great way for anyone responsible for an IP sending mail to hotmail to monitor what traffic Hotmail is seeing from that IP address. This morning I got up to a number of people complaining that […]

Hotmail issues

A number of people, both at ESPs and on the mailops mailing list, are reporting problems at Hotmail. The most common reports are senders getting Site hotmail.com (65.55.92.152) said in response to MAIL FROM (452 Out of memory) during the SMTP session. There isn’t much senders can do about this. Hotmail is going to have […]

Hotmail moves to SPF authentication

Hotmail has recently stopped using Sender ID for email authentication and switched to authenticating with SPF. The protocol differences between SenderID and SPF were subtle and most senders who were getting a pass at Hotmail were already publishing SPF records. From an email in my inbox from September: Authentication-Results: hotmail.com; sender-id=pass (sender IP is 65.55.240.72) […]

Outlook.com

The big news in email today is Microsoft’s announcement of the next version of Hotmail: Outlook.com. This does appear to be an attempt to compete with a host of Google’s offerings. Not only does Outlook.com include Skype and access to social media accounts, but it also includes web app versions of Word, Excel and Powerpoint […]

Email marketing OF THE FUTURE!

ISPs are continually developing tools for their users. Some of the newer tools are automatic filters that help users organize the volumes of mail they’re getting. Gmail released Priority Inbox over a year ago. Hotmail announced new filters as part of Wave 5 back in October. All of these announcements cause much consternation in the […]

Hotmail fights greymail

I’ve heard a lot of marketers complaining about people like me who advocate actually purging addresses from marketing lists if those addresses are non-responsive over a long period of time. They have any number of reasons this advice is poor. Some of them can even demonstrate that they get significant revenue from mailing folks who […]

Changes at Hotmail

Microsoft announced a number of changes to the Hotmail interface today. It doesn’t look like this will affect how mail is received, but will affect how users can interact with it. As always, the best advice I can give you is send mail people want and like.

  • AOL compromise

    Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something. Details are hazy, but there seems to be quite a bit of noise surrounding this incident. AOL hasn't provided any information as of yet as to what is going on.4 Comments


  • ReturnPath on DMARC+Yahoo

    Over at ReturnPath Christine has an excellent non-technical summary of the DMARC+Yahoo situation, along with some solid recommendations for what actions you might take to avoid the operational problems it can cause.No Comments


  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment
