I have an application that uses SmtpClient to generate email after a form is submitted. There are two separate forms, identical except for the form fields. One works exactly right, populating database and sending email. The other populates database but email is never generated. Debugging indicates: A first chance exception of type 'System.Net.Mail.SmtpException' occurred in System.dll Exception caught in RetryIfBusy(): {0} I do not seem to be able to find any answers regarding what this might actually indicate. Is this an application issue or some kind of smtp server issue?
1) What is the SMTP server set to? It should be set to "localhost" if it is not. 2) I think this is an app error, I have never seen this error before.
