Our mail server at work is still getting attacked by a rumplestiltskin attack and after looking at the whois information it’s the same guy as last time so I think a polite email to abuse and postmaster@systemaccess.se and @comtech-data.se may pay dividends.
Meanwhile, I found a good article on stopping spam with open source software. I must roll some of those Sendmail m4 directives into Install-Sendmail soon.
From the maillog:

Disturbing news this morning. Last Monday night a group of protestors in Dublin were attacked by Gardai, seemingly unprovoked if the people who rang 2fm are to be believed. An RTE reporter at the scene said that Gardai had taken off their ID tags and refused to acknowledge questions about why they were removed.
