Misinformation on filters

I’ve seen reports that someone is asserting that utm=COVID19 in URLs results in all mail going to bulk at multiple ISPs. This is the type of thing that someone says is true and dozens of folks believe it and thus a “deliverability phact” is born. For a plethora of reasons, this doesn’t pass the sniff […]

Deliverability discussion

Lots of folks are socialising distantly these days, so I thought I’d try a scheduled deliverability discussion over video.

Address verification doesn’t fix any real problem

Would you trust an address verification company that used twitter spam to advertise their product? Would you trust an address verification company that sent email spam to advertise their product? Would you trust an address verification company that sent email advertising their product to made up addresses? Would you trust an address verification company that […]

The OSI Seven Layer Model

In the 1970s, while the early drafts of the Internet were being developed, a competing model for networking was being put together by the ISO (International Organization for Standardization). The OSI (Open Systems Interconnection) Model broke the work needed to implement a distributed network service into seven separate layers of abstraction, from the physical infrastructure […]

Some Microsoft thoughts

Right at the end of January, Microsoft appears to have made couple of changes to how they’re handling authentication. The interesting piece of this is that, in both cases, Microsoft is taking authentication protocols and using them in ways that are slightly outside the spec, but are logical extensions of the spec.
