The old memory cells are sparking intermittently on this one.
I think I recall before going through the way some of the messages are handled in Incredimail and noting that the message format makes it just about impossible for avast to insert the “clean mail” messages. However, as I recall, those messages should still contain the X-Antivirus headers denoting that they had been scanned by avast.
There can be times when avast cannot even insert the X-Antivirus headers (and I have had to work with some developers to make that possible).
I confess though that this old email professional has a somewhat prejudiced view of Incredimail and I have yet to be persuaded to give this piece of software houseroom on my system to test it. I have unfortunate experiences of the efforts to remove this thing from the systems of those I support who have (in my view) been unwise enough to install it (the last only a couple of months ago).
