u seem to be confusing 2 different kind of attacks anyway, i'm no expert on the matter, but as far as i know a brute force attack is one that will try every single character from a-z & 0-9 in different combinations until it finds the right password(and will take a very long time), the other type of attack mentioned is known as a dictionary attack and this is the type that works from word lists, i doubt any of them would work on a web based email account and are more useful for getting passwords on a local machine...
