What does 'batch of messages' mean to a mail server? Or more relevant to performance, what kind of ratio of program starts to messages do you expect and can you sort-circuit the startups as soon as you know you are going to discard a virus? MimeDefang runs as a sendmail milter that is always running and doesn't need to restart for each message so it is particularly efficient although spamassassin takes a certain amount of CPU to run anyway. -- Les Mikesell lesmikesell@xxxxxxxxx
