The intent of DMARC is to cause emails to silently vanish. Ideally deploying DMARC would cause all malicious email that uses your domain in the From address, but which has absolutely nothing to with you to vanish, while still allowing all email you send, including mail that was sent through third parties or forwarded, to be delivered. For some organizations you can get really close to that ideal...
We often say that a blacklist has “listed the world” when it shuts down ungracefully. What exactly does that mean, and why does it happen? Blacklists are queried by sending a DNS lookup for an A record, just the same as you’d find the address of a domain for opening a webpage there. The IP address or domain name that’s being queried is encoded in the hostname that’s...
The SpamCannibal blacklist – one that didn’t affect your email too much but which would panic users who found it on one of the “check all the blacklists!” websites – has gone away. It was silently abandoned by the operator at some point in the past year and the domain registration has finally expired. It’s been picked up by domain squatters who, as usual, put a...

There’s going to be a lot of hype today about something the security researchers who found it are calling “EFAIL”. Interviews, commemorative T-Shirts, press tours, hype. The technical details are interesting, but the un-hyped end-user advice would probably be “If you’re using a mail client that’s got bugs in it’s MIME handling, and you’ve configured...
We sent out some W-9s this week. For non-Americans and those lucky enough not to have to deal with IRS paperwork those are tax forms. They’re simple single page forms with the company name, address and tax ID numbers on them. Because this is the 21st Century we don’t fill them in with typewriters and snail mail them out, we fill in a form online at the IRS website which gives us PDFs...
Update: The issue seems to have been resolved and Laposte say they’re no longer sending the 519 responses as of April 25th 2018. Laposte.net are having a bad couple of weeks. There’ve been reports from customers of their IMAP service being unusable, with attempts to move or delete messages timing out and expected emails simply not arriving. Several delivery friends have mentioned that...
There’s a lot of discussion going on about just what GDPR requires, and of who, and in which jurisdictions. German organizations in particular have been more aggressive than most about wanting to see opt-in confirmation for years and now seem to be adding “because GDPR” to their arguments. I’m still not sure how this is going to shake out, but I’m beginning to see...
Vala from Salesforce shared this infographic this morning.

Email is still a pretty vibrant messaging channel.
I got a piece of B2B spam last week that showed in several different ways why spam isn’t going away any time soon. Systemic problems dealing with abuse at scale at Google. Ethics problems at Cloudflare. Problems dealing with abuse at scale at Amazon. Cultural problems in India, several times over. Buckle up. The spam content The spam email itself looks pretty much like any business email...
