If you are using Outlook (at least a modern version of it - after Office 2000) then it is recommended that you use the avast Outlook plugin. If you use the plugin then Outlook will pass each message to avast for validation before it is added to the message store (and it has nothing whatsoever to do with the type of connection you have from Outlook to the message server). It is not scanning the connection; this is a program level connection between Outlook and avast.
This way you can forget all about STunnel.
