You’re going to be seeing a lot of discussion about email addresses stolen from ESPs in the next few days, if you haven’t already. There are a lot of interesting things to discuss about that from an email perspective – from “Why two factor authentication isn’t a magic bullet.” to “And this is why corporate spam folders can be a major security risk.”...
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 I do what most recipients do in that situation (well, the ones who...
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.
… or Find the False Positive. Anyone sending a lot of email has complained about spam filters and false positives at some point. But most people haven’t run a mailbox with no spam filters in front of it in recent years, so don’t have much of a feel for what an unfiltered mailbox looks like, how important filters are and how difficult their job is. I run no transaction level...
I have a new laptop, so I’m having to teach the spellchecker some words it doesn’t know.
deliverability, unsubscription, MAAWG, DKIM, epending, ESP, smarthost, return-path …
There sure are a lot of words in the email business that outsiders might not recognize or understand.
I received an email yesterday with the subject “Please confirm your lunch reservation”. It didn’t look like a typical spam subject line, but wasn’t from anywhere I recognized. I take a look. I’ve reserved a seat for you (and up to 2 guests from Word) at your choice of upcoming, complimentary lunch seminars that I will be hosting around the Bay Area … Sure...
I’ve had a couple of people ask me about MIME structure recently, especially how you create multipart messages, when you should use them and which variant of multipart you use for different things. (And I’m working on a MIME parser / generator for Abacus at the moment, so it’s all fresh in my mind) So I’ve put together a quick cheat sheet, showing the structure of four...
My Mum flew in to visit last week, and over dinner one evening the talk turned to email. We don’t get much spam on Yahoo, mostly because we don’t give our email address out much. The only spam we really get is from <stockbroker website>, and that all goes to the spam folder. We use the site for checking stock quotes – it’s free, and we never see any of the spam they...
We’ve just about run out of the Internet equivalent of a natural resource – IP addresses. ICANN allocated the last couple of blocks of general usage IPv4 addresses to APNIC earlier today. There are just five usable blocks of addresses left, and they’re reserved by IANA policy for the final phase of IPv4 exhaustion, one for each RIR. Like any other resource that’s been...
A client of a friend was getting rejection messages when they tried to send mail Google tried to deliver your message, but it was rejected by the recipient domain.
