.vg/.biz

Very little email spam actually gets through to me any more. OS X’s Mail.app weeds out about 40 a day based on content, leaving about three a day that consist entirely of inline JPG images. Which Mail.app doesn’t load.

The subject lines make it clear that they’re obvious spam, so my latest trick is to view the raw source, look for the link to the picture, and add that domain to a custom rule. For the past few weeks, virtually all of these have been links to sites in the .VG top-level domain. From the host names involved, it’s clear that the registrar is in on the scam, so I’ve junked all messages containing “.vg/”. Works like a charm.

Today, a few got through with .BIZ domains, and I realized that I’ve never seen a legitimate business that had a .BIZ domain. So I added “.biz/” to the list as well.

The rule also junks messages containing “http://1” through “http://9”; I think that one still catches about ten spams a day.
