How to send email via smtp using VB.NET 2010

I need to send an email via SMTP, I have my SMTP in a Linux Centos Server, and I created the software to send emails with VB.NET 2010.

After using the namespace : System.Net.Mail.SmtpClient, I receive an exception :

Mailbox name not allowed.
The server response was: sorry,开发者_StackOverflow社区 that domain isn't in my list of allowed rcpthosts (#5.7.1)

Thanks in advance.

That's an error from the server you're attempting to send the email to; it has nothing to do with your code. The server you're trying to send the email too probably isn't authoritative for the mail domain you're sending to.
