I personally use this as a simple way of preparing quality combos for my targets.
This simple regex check will take in ur email-ass lines and check to make sure the email is valid (contains at minimum 2 characters before and after the @)
For the Success line it will check for a minimum of 8 characters. Of which one has to be uppercase and one has to be a number. You could edit it yourself and have it check for special characters as well.
