The SMTP or POP3 protocol (cant remember which) used to support the
ability to connect to the server and verify if a username exists
before delivering the mail. But this feature was abused and was used
for spamming so it is now disabled on all major servers (it's probably
disabled by default in all servers anyway).
There is no way to verify (without sending an email) if the email will
be received in a mailbox.
