Hi,
I have a MVC .NET 3.5 application that is using the SmtpClient to send
email. We have been receiving several 'System.Net.Mail.SmtpException: The
operation has timed out.' errors over the past few weeks. From that we
can tell the destination server is not accepting our initial connection and
then the attempt times out. I have a couple of questions around this
scenario, one being do we need to manually code retry attempts, or should the
SMTP server handle retires, and in regards to the second question if we do not need to code
retry attempts do we need to make sure our message contains any specific
information that tells the SMTP server to retry? From several attempts we
have noticed that if we sent mail directly from Outlook it does arrive successfully (maybe after a delay), but if
it's generated from the application server and the sent for delivery it times
out.
Thanks
