Supreme Court declines to hear anti-spam case

Yesterday the Supreme Court declined to hear an appeal for Virginia v. Jaynes. This means that the Virginia state supreme court ruling overturning the Virginia anti-spam law currently stands. Jeremy Jaynes was a well known spammer who went under the name Gavin Stubberfield. He was pretty famous in anti-spammer circles for sending horse porn spam. […]

Delivery can be counter-intuitive

We all know that receiving ISPs rate limit incoming email. With the volumes of mail that they’re currently dealing with they must do that in order to keep their servers from falling over. A client was dealing with rate limits recently. These were not typical rate limits, in that the recipient ISP was 4xxing mail. […]

Fake privacy policies

I sign up at a lot of websites and liberally spray email addresses across the net. These signups are on behalf of one customer or another and each webform gets its own tagged and tracked email address.

What is an email address? (part three)

These will exclude some legitimate email addresses, but not any that anyone is likely to actually be using. And they’ll allow in some email […]

Yesterday I talked about the technical definitions of an email address. Eventually on Monday I’m going to talk about some useful day-to-day rules about email address acquisition and analysis, but first I’m going to take a detour into tagging or mailboxing email addresses. Tagging an email address is something the owner of an email address […]


What is an email address? (part one)

Given we deal with email addresses every day, dozens or thousands or millions of them, it seems a bit strange to ask what an email address is – but given some of the problems people have with the grubbier corners of address syntax it’s actually an interesting question. There are two real standards that define […]


ISP Information pages

I have posted a ISP Information Page. Right now it contains links to Postmaster pages, Whitelist signup pages and FBL signup pages. I have some ideas on what information would be helpful to add, but would like to hear what types of info people would like to have easy access to. What do you think […]
