Everytime I startup, I got a popup saying [port 25 is being used by another program] Go to help and change settings if your NOT using Outlook/Exchange. However, I do use outlook. So changing and playing with that [avast4.ini] file did not help. Also using TCPview tool did not give me any clue to solve. A lot of information but no program using port 25 which seems to have the most priority to use it or which is going to use it initially when I start up.
