Yahoo always returns a 250 response no matter what.

Their are two methods that I use to validate a Yahoo email account, 
other than sending an email. One if to try to sign up using that id 
(ffmmortgageco2) at 
http://edit.yahoo.com/config/eval_register?.v=&.intl=&new=1&.done=http%3a//mail.yahoo.com&.src=ym&.partner=&.p=&promo=&.last=

If that id is available, you know that the email address is not valid. 
If the id is used, it may or may not be valid.

I then check to see if there is a profile for this account at 
http://profiles.yahoo.com/ffmmortgageco2

If it returns something like this profile can not be found (it's been 
awhile so I don't recall the wording) it means that the account has been 
deleted. If it shows a profile, with information or not, it means that 
the account is valid.
