I’ve seen several reports of unexpected rejections for unauthenticated email to Google over IPv6 today. Unauthenticated mail over IPv6 is a bad idea, but Google usually spam folders it rather than rejecting it. The Gmail status dashboard is reporting an issue “Some messages sent to consumer Gmail accounts are being rejected due to authentication enforcement” so something […]
Len Shneyder writes about what we can expect to see in the near future email landscape.
The FCC recently published a notice of proposed rulemaking that will have an impact on how we fight abuse on the internet. M3AAWG has submitted a comment on the proposal (pdf link). All submissions can be found on the FCC website.
Hotmail seems to be having a bad day, responding to a lot of delivery attempts with “554 Transaction failed” responses. It’s not you, it’s them. They’re aware of the issue.
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 […]
If you’re sending email from any address beginning with a 65 – in 220.127.116.11/8 – 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).
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.
Over on the Farsight Security blog Joe St. Sauver talks about some of the early days of online abuse, on usenet. Laura and I were on the periphery of early usenet abuse, mostly as users, but Usenet (and IRC) around then were the places we both started with email abuse.
I’ve been hearing from folks over the last few days that they’re seeing an uptick in deferrals from Yahoo! The deferrals are not uniform. ESPs report they’re seeing some, but not all, customers affected. Other ESPs aren’t seeing any changes. It’s not just you. But it would be very worthwhile to dig into engagement and […]
Good news for Sender Score Certified IPs. Return Path recently announced that AOL has joined the list of ISPs offering preferential treatment to certified IPs.
