Re: Using System.Net.Mail

That looks right to me.  In my case I have to use the fully qualified
name of the SMTP server, so if the server is called smtp1, I have to use
"smtp1.jwu.edu".  Perhaps that would help?

Alternately, if you weren't specifying an external mail server
previously, it may have been using a local SMTP server.  Perhaps there's
a firewall setting on the SMTP server that's preventing a connection
from the machine this is running on?

I don't think it's a problem in your code.



-----Original Message-----

string to = "[email protected]";
string from = "[email protected]";
MailMessage message = new MailMessage(from, to); message.Subject =
"Using the new SMTP client."; message.Body = @"Using this new feature,
you can send an e-mail message from an application very easily.";
SmtpClient client = new SmtpClient(Server); client.UseDefaultCredentials
= true; client.Send(message);

When the Send is executed this exception is raised:
"An established connection was aborted by the software in your host
machine "

Looking further, the status code given is "GeneralFailure", the
exception message is "Failure sending mail." and the inner exception
message is "Unable to connect to the remote server".

The problem may or may not be centered around the server name.  It's a
server on our intranet, and I have tried both its name and its IP
address, but no joy.
