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 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. No Comments


  • Fixing discussion lists to work with new Yahoo policy

    Al has some really good advice on how to fix discussion lists to work with the new Yahoo policy. One thing I would add is the suggestion to actually check dmarc records before assuming policy. This will not only mean you're not having to rewrite things that don't need to be rewritten, but it will also mean you won't be caught flat footed if (when?) other free mail providers start publishing p=reject.No Comments


  • Sendgrid's open letter to Gmail

    Paul Kincaid-Smith wrote an open letter to Gmail about their experiences with the Gmail FBL and how the data from Gmail helped Sendgrid find problem customers. I know a lot of folks are frustrated with Gmail not returning more than statistics, but there is a place for this type of feedback within a comprehensive compliance desk.No Comments
