I have Squid running in transparent mode on our Linux-based firewall: # squid -v Squid Cache: Version 2.5.STABLE9 configure options: --enable-storeio=diskd,ufs --enable-linux-netfilter --enable-removal-policies=heap,lru --enable-delay-pools Is there a way to have Squid snag all email attachments downloaded from various webmail services and save it to disk for a virus scan, or better yet, scan it automatically and only forward it on to the client if it's clean? I have adzap running already and don't want to interfere with it. The redirect code is toward the end of squid.conf: redirect_program /usr/local/adzap/scripts/wrapzap Is there a simple redirector out there that I can stick in there after adzap has done its job, pull out email attachments, and do stuff with them before forwarding them on to the client? Thanks.
