    I'm honestly not sure how it does it nowadays - in the old days a lot of AV
    software would replace the server names with localhost to run a little proxy
    for scanning. It's more sophisticated now and actually *works*, which it
    didn't used to!

    You can disable mail scanning if you want (I don't, myself). Any reason
    you're shutting down your AV anyway?
