I've been running an amavisd-new, spamassassin, postfix setup for a while to help crush spam on our incoming e-mail servers. The setup I'm using is a few years old at this point and its about time to rebuild on new hardware.
I was wondering if there was another approach to tackling this ever-present issue that might yield better results for our large mail system. I have no particular complaints about the current setup, other than the fact that we still are plagued by spam... :)
I'm mostly interested in free solutions, but might be willing to consider a paid software/third party service if the price is right.
Thanks in advance for any suggestions you might have.
