SmtpClient est disposable ?
public class SmtpClient : IDisposable
The SmtpClient class has no Finalize method, so an application must call Dispose to explicitly free up resources. The Dispose method iterates through all established connections to the SMTP server specified in the Host property and sends a QUIT message followed by gracefully ending the TCP connection. The Dispose method also releases the unmanaged resources used by the Socket and optionally disposes of the managed resources.
Call Dispose when you are finished using the SmtpClient. The Dispose method leaves the SmtpClient in an unusable state. After calling Dispose, you must release all references to the SmtpClient so the garbage collector can reclaim the memory that the SmtpClient was occupying.
