No, as long as things are OK there is minimal aditional output. You'll just get a few lines when the number of slaves changes (aditional slave started or running slave killed because of timeout). if the settings for minimal /maximal number of slaves is reasonable for your system this shouldn't happen often.

what's the overhead incurred by the scanner? for each message mimedefang will call the scanner once to check the whole message and if something is found one again for each attachment. starting a virus scanner can be quite an expensive operation.

I've been quite happy using kaspersky virus scanner in daemon mode; does something similar to mimedefang-multiplexor, only for virus scanning, greatly increased the number of messages/second my server can handle.

I've attached a patch to mimedefang.pl to make it work with the kaspersky scanner in daemon mode instead of normal commandline mode.

Bye, Martin
