the AutoRedirect=0 just stops the catching of all outgoing connections. It does not stop the mail scanning service and you should be able to use it normaly as in ver. 4.1 (if you direct your mail clients to localhost - or run Pop Wizard (avast4\ashPopWz.exe).

Please check, that the “avast! Mail Scanner” service is running. You might also start it manualy by the command:

net start “avast! Mail Scanner”

Also you might have some port conflicts with your local mail server. (not very probable thou, as you upgraded from working setup). Please check this thread (among others) for help on how to change listening ports. http://forum.avast.com/index.php?board=2;action=display;threadid=9019
