Whats configured into your MTA?

I was wondering the web looking at random items, when I came along an article at http://www.worldwidecreations.com titled Stopping spam before the door with SpamCop and IPTables Its a great article with a lot of information and code on how the author is able to grab the offending hosts and place them within IPTables.

Its a great article with a lot of information and code on how the author is able to grab the offending hosts and place them within IPTables.

One thing that I really can’t agree with is the use of IPTables to block mail traffic from an RBL that has in the past and present block many legitimate hosts and email. I’d rather have spam to my account marked as spam so that I can be the judge and correct any false positives. At the moment, all my mail using using Exim with sa-exim (SMTP time spamassassin scanning). This allows for messages to be bounced back at SMTP time!

What is everyone else using for an MTA and how are you filtering spam?

Seagate unveils turmoil-proof EE25.2 hard drive - As if stuffing a quarter terabyte onto a single Barracuda platter and finally matching Hitachi in the 1TB realm weren't enough to gloat about, Seagate is now unveiling a hard drive aimed squarely at those reading this from the Amazon Rainforest (or a vanilla construction area, but you understand). The second-generation SATA EE25 drive -- easily dubbed the EE25.2 -- is available in sizes up to 80GB and can handle extreme temperatures, sensational heights, 'round the clock operation, 90-percent humidity, and drops / shocks that would likely put you out of commission before your data. No word yet on pricing nor availability, but don't expect 80 gigabytes of nearly indestructible storage to come without a premium.
