If they are run in series, then wouldn't it be best to run the next scanner only if the previous scanner passed? In other words why scan the email again if it already failed one of the scanners?

They are run in series. Since the virus scanners typically use up as close to 100% of the CPU time that they are given, if we switched to running them in parallel, an improvement would only be shown on servers with multiple processors. However, it typically takes a virus scanner less than a second to scan all the attachments, so even on a multi-processor server, the increased delivery speed would probably not be noticed. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers.
