When I switched to my new Slicehost server, I spent a while trying to decide what I wanted to do about email for my domains. I contemplated using Google’s domain email service, or some other third-party email hosting. But I just hated giving up that much control of my email setup. [...]

Thank you for continuing to submit your data to my anti-spam systems. I have been able to put your information to very good use, keeping my blogs and email practically spam-free 24-hours a day. The emails, comments, trackbacks, and referers that you submit are analyzed for key spam indicators, which I can then use to automatically block your servers so that your future spam attempts don’t even reach my web server.
Eventually, I hope to share my collected anti-spam knowledge to a wider audience, via WordPress plugins and web services available to the general public. [...]
I only had a couple of responses to my call for SpamValve testers. One of the testers has already begun using SpamValve on his FreeBSD server. The other is tied up at the moment, but is going to attempt to adapt it to work on a Linux server sometime next week.
In the meantime, I’ve started using it to filter spam hits to my mail service. This was accomplished with a one-liner:
tail -0f /var/log/maillog | \
perl -e 'while(<>){ m/Mail from (.*) rejected/; \
system("/usr/local/sbin/svupdate", $1) if $1;}'
The command above watches the end of my sendmail log for entries indicating messages rejected by RBL checks. [...]
I think I’m almost ready to let some other people bang on SpamValve. I want to get a closed group of users to try it out and give me some feedback before I release it to the general public. If you’re interested in testing it, and meet the requirements below, contact me.
Requirements:
- Requires root access on your server.
- Currently requires the ‘ipfw’ firewall system (I’m on FreeBSD). But if you think you can modify it to work with ipchains or some other firewall, feel free to give it a try. [...]

Follow you, follow me
Two years ago today, we released WordPress version 1.5. This was a pretty major release that introduced several new features that are still major staples of the current 2.1 branch: the Dashboard, Themes, and Pages. It also added a minor new change which was mildly controversial to some: comments were automatically flagged with the ‘nofollow’ attribute.
The
rel="nofollow"idea had good intentions: to give content producers a way to link to another site without implying that they approve of it. [...]
