Subject: quick Postfix check for Outlook date exploit
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 ;-)
