Check credentials for SMTP server

Question

I want to make a program to check mail and password match or not.

SMTP.Credentials = New System.Net.NetworkCredential(email, pass)
SMTP.Send(emailMessage)

I can check send Ok mean match, can not send email and pass dont match. But hope you show me better method.thanks

With _"to check mail and password match or not"_, do you mean you want to verify whether the user identified by `email` and `pass` is allowed to connect to the server specified in `SMTP` and send an email message? — CodeCaster, Nov 12 '13 at 13:31
If that is the case, this is a doppelgänger of [How to validate smtp credentials before sending mail?](http://stackoverflow.com/questions/2426098/how-to-validate-smtp-credentials-before-sending-mail-in-c). — CodeCaster, Nov 12 '13 at 13:34

You cannot check credentials without attempting a send. If the send fails, it will throw an SmtpException. You could check the SmtpStatusCode property for more detail.

This is a limit of the .NET class, not the SMTP protocol. See http://stackoverflow.com/questions/2162932/how-can-i-sort-of-ping-an-smtp-server-so-i-can-check-if-the-account-password-i?rq=1 – Colin Pickard Nov 12 '13 at 13:43
Do you know other method? – Huy Nguyen Nov 12 '13 at 14:00
