qmail is a modern SMTP server; a mail transfer agent. (For the non-technical among you: its the software that delivers your e-mail; a post officer.) It was written as a replacement for sendmail, the conventionally used package for a long time.

I once belonged to the church of sendmail, oh my brothers and sisters, and I was almost confirmed and baptized into its ranks, but I never really believed what I preached, and I always felt deep inside that something was wrong. I was Saved in 1997 when I worked at an ISP that was using qmail; I cast off my sendmailish ways and saw the light.

Since being "saved", I have learned a lot about qmail; its configuration and administration, the technical and design issues that led to its creation, the social issues in using it, and the community of people surrounding it.

These are the various pages on my site related to my dealings with qmail:

• qmail anti-spam HOWTO
  a comprehensive guide to anti-spam philosophies and methodologies, parts of it from a qmail perspective. As far as I know, the only such guide of its kind.
   
• qmailadmin html templates for Dreamweaver [49K, tar.gz, current for qmailadm 1.0.6]
  if you've used qmailadmin, you know how much of a pain it can be to update the design and layout of the template pages they distribute. Well, I finally took the time to put all of them in Dreamweaver templates. Now, with Dreamweaver (or with your homegrown template parser), you can easily update the design of your qmailadmin site. (Please don't use the default Summersault design without asking.)
   
• origip.pl
  an ever-so-simple perl script I wrote to parse the "Received from" IP address out of qmail headers
