SMTP provides VRFY and EXPN verbs to check if an account or mailing list exists. However, most server admins disable these verbs from their mail configuration to prevent hackers from exploiting user lists. Gmail and Yahoo are said to have VRFY disabled.
Another option you can try for these servers is emailing the user with a link to confirm their email address. Granted, it is not as sexy as realtime email verification, but it is more secure for all parties.
