Here is a boolean function that you can put in your JavaScript to check weather the emails are valid (this regex has a ~95% success rate):

function isValidEmailAddress(emailAddress) 
{    
    var emailPattern = new RegExp(/^[-a-z0-9~!$%^&*_=+}{\'?]+(\.[-a-z0-9~!$%^&*_=+}{\'?]+)*@([a-z0-9_][-a-z0-9_]*(\.[-a-z0-9_]+)*\.(aero|arpa|biz|com|coop|edu|gov|info|int|mil|museum|name|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}))(:[0-9]{1,5})?$/i);
    return emailPattern.test(emailAddress);
}

Note that this does not check whether they exist or not, but will help in weeding out false emails.

Send an email to each of them. If you don't get a bounce back then the email is probably valid.

Detect the bounces and remove the addresses that bounce from your list. There is no other way, and the overhead is neglectable.

No, pretty much all email servers will refuse to tell you if an address is valid or not these days since otherwise it would be abused by spammers.

I've used Max Prog for this problem before.
