About 90% of the email I receive is spam. Spamassassin
does a great job of blocking this spam, but it is still consuming
a huge amount of bandwidth.
My current ideas to prevent this are:
1) retire existing email addresses (a very big headache)
2) reply to all spam with fake bounces (most spam has fake addresses and this just increases bandwidth usage)
3) switch from postfix to exim, so that I can block spam at smtp time.
(If someone has tried this, does this have any effect on the total amount of spam?)
Does anyone know of any other way to potentially reduce the initial pre-filtered amount of spam?
Thanks,
Jon.

with MailScanner (www.mailscanner.info) you can decide what to do with the spam. Delete it, bounce it, quarantine it...
MailScanner is a bit like AMaVis, in that it wraps around SA, anti-virus engines and the MTA to provide a higher number of checks.
If you use MailWatch (mailwatch.sourceforge.net) in combination with MailScanner you can also have a HTML based interface for inspecting the quarantine areas and releasing email, or teaching the bayes engine about wrongly tagged email..
