when you connect to an SMTP server you might use the VRFY command.
Syntax:
VRFY username
Explanation:
This command will request that the receiving SMTP server verify that a given email username is valid. The SMTP server will reply with the login name of the user. This feature can be turned off in sendmail because allowing it can be a security hole. VRFY commands can be used to probe for login names on a system. See the security section below for information about turning off this feature.

There is one big problem for you. The gross of the email servers does not allow a client to use the VRFY command because of spammers.
