For pop3 clients, OE, Thunderbird, etc (not Outlook and the Bat as Alan mentions), the Internet Mail provider, the email scanners uses a proxy so it intercepts ports 25, 110, 119 and 143 and scans them first before they are sent on there way or saved into the inbox.
To me I don’t see any beginning middle or end, the avast email scanner intercepts the email at that time you will see the avast email scanner icon in the system tray and subsequently in your inbox or sent items mail box.
