In a blog post on April 28, AOL pointed to their new Sender Best Practices document. These are not things a sender must do in order to get mail delivered to AOL, but rather things that will help improve your reputation at AOL. The recommendations are what I have been recommending for a while and […]

Sanford Wallace (the spammer that prompted me to start figuring out how to read headers) lost his suit with MySpace for failure to comply with court orders and failing to turn over documents. Scott and Steve Richter are in […]

Troubleshooting a Postini block

Mail from one of my clients is being filtered at Postini and they asked me to look into this. Not that there is anything that can be done, of course. Even before they were bought out by Google, they were the poster child for a spam filtering company that believed they could do no wrong. […]

Recently there has been a massive uptick in forgeries. I have been seeing hundreds of bounce back messages, peaking at more than 1000 in an hour. I have been talking about this with people who monitor large spamtrap feeds, large MTAs and spamfilters and it seems this is not an isolated experience. The consensus seems […]

That’s spammer speak

I’ve been hearing stories from other deliverability consultants and some ISP reps about what people are telling them. Some of them are jaw dropping examples of senders who are indistinguishable from spammers. Some of them are just examples of sender ignorance. “We’re blocked at ISP-A, so we’re just going to stop mailing all our recipients […]

  • 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
