Subject:                quick Postfix check for Outlook date exploit
To:                     [EMAIL PROTECTED]

Hi,

With a little help from Koos van den Hout I made a small 
header_check
for Postfix to prevent people from exploiting the latest Outlook bug.
A quick test shows it works but don't come complaining when it 
doesn't
;-)

In your main.cf put this line:

 header_checks = regexp:/etc/postfix/header_checks

(path depends on where your postfix config lives)

In header_checks put:

 /^Date:.{60,}$/ REJECT

This will reject messages with a date line longer than 60 chars.

Don't forget postfix reload ;-)
