Thanks Mark, that sounds like good advice. Will go with that for now. Incidentally, I did notice that a backup scanner has been catching some emails with those lovely little .gif files attached. Apparently kapersky is set as a backup scanner, but I did nothing to set it up that way. I notice that they let you download the rpm, but charge a subscription fee for a key to enable their service. Not what I need for now. I'll start with clam-av.
You can also adapt or extend the filters in amavis to catch email attachments by file type. See the lines around 146 and following in the config file ("# for $banned_namepath_re, a new-style of banned table"). A crude method, but effective if there is a new scare going round about, say, infected jpegs or gifs. I've uncommented the # banned ext - long for my machine, for example. :) Fish
