With postfix 2.x you can do mime_header_checks for "dangerous extensions" in the Content-Type/Content-Disposition and body_checks for the "MS executable MIME fingerprint"On Sat, 27 Sep 2003, Pim Bliek wrote:I get the virii with 3 different content-types: application/x-msdownload,audio/x-wav,audio/x-mid so, just exe doesnt seem to cover it.But how do you filter them out using postfix? PimI was commenting that you can not just check on .exe becasue the virus is not just in .exe files. I was suggesting to check the message body for this line. I do not know about postfix. sorry. -K
http://sbserv.stahl.bau.tu-bs.de/~hildeb/postfix/postfix_sobigf.shtml I'm running 1.x, so I only do body_checks.I feel like I'm in a bit of a delima there though, because I want my gateway mail server to be stable and supported by the security team, but I want the newer features of the later versions so I can make better inbound SMTP decisions. Same goes if I chose to use exim, I'd want v4.
