Does anyone know if it's possible to block certain file extensions within email attachments. In particular, regarding the KLEZ virus and virus related files such as exe, scr, pif, etc.This would be on a RaQ3 server.
Try procmail. It will do what you ask. It might be better to have an antivirus software package on the server though. Virus' are coming through as embedded files and not always attachments. I use a Klez recipe that removes about 90% of the Klez that come to my server. A few do get through and my antivirus software catches them. I also have a recipe to remove the Sircam virus.
