AOL publishes sender recommendations

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 […]

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. […]

Forgery and spamware

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 […]

  • DNS problems

    Hurricane Electric had a significant outage of their authoritative DNS servers this morning, causing them to return valid responses with no results for all(?) queries. This will have caused delivery problems for any mail going to domains using DNS - which will include some of their colocation customers, as well as users of their free services - but also will have caused reverse DNS to fail for most servers hosted by Hurricane Electric worldwide, so if any of your mail is being sent from HE hosted machines you may have seen problems. (We're HE customers so we noticed. Still happy with them as a vendor.)No Comments

  • DNS issues

    If you're sending email from any address beginning with a 65 - in - it's possible you'll see some delivery problems. Something appears to be broken with dnssec signatures for the reverse DNS zone, leading queries for reverse DNS to fail for anyone using a dnssec aware DNS resolver (which is almost everyone).1 Comment
