Smtp client for Visual Studio 2010

Question

Hi.

I have problem with send email from WPF application making in Visual Studio 2010.

First I used SmtpClient .Net class but this class  not connected to many email servers. I have problem with authentication. All mail programs connected to all email servers. SmtpClient not connected on the same parameters.

Do you have some control to send email from c# application?

I used vmime.net control but it not connected to all servers.
