Authentication and phishing

Yahoo announced today that they are releasing the Yahoo! Mail Anti-Phishing Platform (YMAP) that will help protect their users from phishing. They have a similar project in place for eBay and PayPal mail, but this will extend to a broader range of companies. [W]e’re beefing up Yahoo! Mail’s SpamGuard by adding more security measures that […]

Does your unsubscribe process work? Are you sure?

I stumbled across an interesting problem today. A company I bought something from a while back added me to their newsletter. They seem to be having trouble making sales this quarter, as they’ve gone from an occasional email every few weeks to bombarding me with increasingly desperate offers in the past week or two. So […]

Just give it up already

I have a mail system totally separate from my inbox to use when I’m testing signup forms. Some of them are client, some of them are vendors my clients are thinking about using. In any case, it’s mail I’m seriously concerned won’t stop just by me opting out of it. The server hosting that mail […]

Spammers, eh?

From my inbox, missed by the spamfilter: Do you know people who have worked a lot or could not find a job for a long time and suddenly began to earn well, gain valuable items and look better? We can reveal to you their secret. Anyone who bought a diploma from us raised their standard […]

Holomaxx v. MSFT and Yahoo

I mentioned way back in January that Yahoo had filed a motion to dismiss the case against Holomaxx. Microsoft filed a motion to dismiss around that time, although I didn’t mention it here. And, of course, Holomaxx filed a motion in opposition in both the Microsoft case and the Yahoo case. Nothing terribly interesting here, […]

Letters to the abuse desk

Ben over at Mailchimp has shared some of the mail that comes into the mailchimp abuse desk. It’s a post well worth a read. One of the things that leaped out at me during that post is that the positive emails highlight how much the Mailchimp delivery and compliance people help their users get good […]

Getting it so wrong

One of the things I notice is when vendors send me badly formatted emails. There’s one vendor of ours that gets it so wrong I find it offensive to receive their mails. Not only have they not managed to invoice or process payments correctly for months, but their billing emails come to me with one […]

SORBS Progress

A little bird tells me that GFI have resolved their primary blocking issue on SORBS problems. If all goes well I’d expect their infrastructure and policies to improve significantly over the next few months. We’ll wait and see whether the data quality begins to improve after that.

  • HE.net 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 HE.net 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


  • 65.0.0.0/8 DNS issues

    If you're sending email from any address beginning with a 65 - in 65.0.0.0/8 - 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


  • Our green bar certificate is going away

    Later today we'll be switching from an Extended Validation ("green bar") SSL certificate to a Domain Validation certificate. This isn't exactly a planned change but I'm waiting for responses from Comodo before I go into it too much. I'll share some more details next week.3 Comments
