I added a page to this blog, detailing some of the tricks I use to keep spam at a minimum level. The first part talks about Sendmail tricks I found here and there on maling lists and web sites. I take this opportunity to thank the authors.

It seems to me it is more efficient to fight spam at the SMTP session level. This saves CPU cycles, bandwidth and disk space. Spam filtering at a later stage, typically at the delivery agent or at the mail reader is less efficient. From the spammer’s point of view, if the message got past your SMTP gateway, then there is a chance that someone will read it.

I will add and/or detail these tricks in the coming weeks.

Until we have ISPs really commited to eliminate spammers from their network, either on their own initiative or being forced to by governments, the best thing we can do is to frustate the spammers as much as possible so as to make their business unprofitable.
