Top Dog automatically detects all your email accounts.

There is no need to tell Top Dog what email accounts you would like to screen and you do not have to change any settings in your email program.
When your email program first checks an account Top Dog will automatically detect all your account settings regardless of the email program you use.

Upon install Top Dog will also automatically scan your address books and whitelist all the people found in it.
It will also scan your "sent items" folder and whitelist all the people you have ever sent mail to.
This ensures that Top Dog will never mistake email from these people for spam.
