> Good idea. But how should i block file types at smtp level on qmail? There is the excellent patch by Russell Nelson that blocks mails based on base64 signatures in MIME parts. Get the patch from: http://www.qmail.org/qmail-smtpd-viruscan-1.3.patch and see the short documentation at the start of the diff for usage instructions. But notice: This patch does block mails based on content not file types. So you can't say: "block *.exe files" but "block attachments that start with TVqQAAMAA in base64". We reject a lot of virus mails before they even come near the virus scanner.
