    ************** JIT Debugging **************
    To enable just-in-time (JIT) debugging, the .config file for this
    application or computer (machine.config) must have the
    jitDebugging value set in the system.windows.forms section.
    The application must also be compiled with debugging
    enabled.

    For example:

    <configuration>
        <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.


    is error or where its coming from.

  • So "The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 ".  So you need to find out what kind of authentication it supports, perhaps by talking to its administrator, and see whether SmtpClient supports that authentication method...

     

    Sometimes the SMTP server checks whether the client has authenticated to the POP3 server recently, if that's the case see the code at http://social.msdn.microsoft.com/Forums/en-US/netfxnetcom/thread/30a85f21-f181-44a4-8230-7a5ec66a7dbb
