On Monday I talked about how big IPv6 address space is, and how many IPv6 addresses will be available to end users. We’re mostly an email blog, though, so what’s the relevance to sending email? If the recipient you’re sending to has an IPv6 mailserver you can send mail to them over IPv6, if you choose to. If they only have an IPv6 mailserver, with no IPv4 mailserver at all then...
IPv6 is big. Really big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist, but that’s just peanuts to IPv6. The old Internet, the one you’re probably using right now, runs on IP version 4. IPv4 addresses have numbers and dots; they look like 172.224.4.56. There are about 4,009,754,624...
I’m on quite a few mailing lists for companies whose main product is sending gifts: food hampers, jewelry, flowers, overpriced desk toys and so on. They tend to ramp up their volume before appropriate holidays such as Christmas, Mother’s Day, Thanksgiving, Valentine’s Day or Father’s Day and target their promotions to those particular holidays. One recipient may have a...
Google Apps for ISPs is being shut down. While this was a scheduled end of life, apparently some users weren’t notified (always keep the contact email address up to date at your vendor!) and other users were told that it would be discontinued in July and were surprised when their service was turned off a month earlier than they expected. I’ve not seen any reports of mail bouncing due...
iCloud Mail (mac.com, me.com, icloud.com) has a shiny, new postmaster resources page. No whitelist, no FBL, just a good list of best practices to follow for sending bulk mail.
The Conservative Party is one of the largest political parties in the UK. They’re center-right politically (by European standards), nationalist and pro-business. You’ll often see them called the Tory party or Tories – a pejorative nickname they acquired 350 years ago. While they’re part of the ruling coalition today, there’s a general election coming up in the next...
Email Authentication lets you demonstrate that you sent a particular email. Email Repudiation is a claim that you didn’t send a particular email. SPF is only for email authentication1 DKIM is only for email authentication DMARC is only for email repudiation 1 SPF was originally intended to provide repudiation, but it didn’t work reliably enough to be useful. Nobody uses...
We’re seeing multiple reports that the Yahoo feedback loop stopped working some time in the past couple of days. If you’re not seeing reports, it’s not just you.
Thirty years ago this Sunday, symbolics.com was registered – the first .com domain. It was followed, within a few months, by bbn.com, think.com, mcc.com and dec.com. Symbolics made lisp machines – symbolics.com is now owned by a domain speculator. BBN is a technology R&D company who’ve worked on everything. If I had to pick one thing they were involved with it’d be the...
It’s the time of the year, when we celebrate a holiday by telling you about email.
