Using spamd in greylisting mode, I’m running greyscanner to pick off some low-hanging fruit (senders with no A or MX). But I also have an old domain that isn’t used for production any more, and it gets tons of spam. Here’s how I used that to my advantage.

In Praise of a Coffee Cup

Memory File System on OpenBSD on Soekris
