Howdy, If anyone's interested, I've found the following snippet useful for blocking the latest round of Outlook viruses using sendmail. Just remove the LOCAL_RULESETS and add it before the mailer definitions section in sendmail.cf if you're not using m4 config files. You'll need to fix the wordwrap of course. Naturally, use at your own risk, YMMV, etc... --->snip<--- LOCAL_RULESETS HX-Unsent: $>CheckUnsent SCheckUnsent R1 $#error $@ 5.7.1 $: 550 X-Unsent header suggests e-mail virus; please remove virus then resend --->snip<--- Regards, Chris Knight Systems Administrator AIMS Independent Computer Professionals Tel: +61 3 6334 6664 Fax: +61 3 6331 7032 Mob: +61 419 528 795 Web: http://www.aims.com.au To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
