This is slightly off topic, but... As it happens, I run my own email system (and run email for a few other people at the same time.) My email address is also very very widely published, so I'm on virtually every spam list in existence. Thus, I'm reasonably qualified to speak on this. Things work pretty well, and I spend essentially no time on required maintenance. Malware is not a problem. Viruses by email haven't been prevalent for a while anyway, but because I block all windows executable formats in attachments at the SMTP server, back when they were common, none of that traffic got through. 100% coverage. For spam, I use a couple of reliable RBLs, a few simple block rules, and spamassassin for postprocessing. I get almost everything. About ten spams a day get through to me, but on the other hand, I get hundreds of legitimate messages on an average day and my address is _very_ widely published. I think that a zero maintenance box that handles this is probably doable. One could also set up a peer to peer blacklisting/spam reporting and detection system that would reduce the problem further without individual work. All that said, there is a good reason that I proposed that in the long run, whitelist only systems like Jabber and Facebook messaging are a better model. -- Perry E.
