I'm running Postfix on my desktop machine, which directly receives all
incoming mail for my account (there are secondaries configured for when it's

Postfix is configured to reject senders and messages that don't conform to
standards, as is the case with many spam scripts. After that, I use crm114 in
my Procmail configuration to filter out the spam that remains.

I used to run Spamassassin but it became increasingly inaccurate and I was
able to achieve better results by switching to Crm114 and training the
classifier appropriately. Other people with different mail characteristics
will experience different behaviour.
