I want a program that can effectively check if yahoo emails are available. But it will have to sift through a list that has more than one domain of email that is not yahoo.

It will pretty much look like this


Code:
55018:bwahahahahahaha:katbar@doorpi.net
55019:crymarjoh:Crymarjoh@yahoo.com
55020:bowser2003:domonkasshu2002000@yahoo.com
55021:_-Kurai-_:aya_jill@hotmail.com
55023:iridanilightstorm:StarSakura@hotmail.com
55026:elvire:virou@skynet.be
Thats taken from a list I have.
