An unsolicited testimonial I received in my email:
Date: Wed, 07 Feb 2001 08:29:06 -0800 From: ****** To: ***** Cc: jhardin@wolfenet.com Subject: Helpful E-mail for getting rid of Hybris and other net based virii - system admins Here's the deal: I'm a network admin with a few mail servers running Sendmail 8.11. E-mail security has ALWAYS been the highest priority on our security checklist for invasion techniques. Today we were battling with the Hybris worm, behind the scenes... Point blank, we've stopped the following dead, even before the news services caught on to the onslaught: Melissa (all variants) CIH Hermes Hybris ProLin MyRomeo I Love You Navidad New Apt Explore Zip All VBS, SCR, CHM, PIF delivered virii And more... All I can say is: Jason[sic] Hardin's Procmail script http://www.impsec.org/email-tools/procmail-security.html This script has saved myself, and our company well into the ten-thousands of dollars of downtime, productivity, and overall potential destruction by these viruses. It's easy to use, and anyone with a UNIX mail server and procmail should implement this (either sitewide or per user).
Thanks!
