Guest

Hi,

I use the following code snippet in VS 2005

Dim message As New MailMessage("(e-mail address removed)",
"(e-mail address removed)", "Subject", "Message Text")
Dim emailClient As New SmtpClient("10.34.45.135")
emailClient.Send(message)

When I execute the code I get the below error.

System.Net.Mail.SmtpException was unhandled
Message="Failure sending mail."
Source="System"
StackTrace:

Do you have relay rights through the IP address 10.34.45.135? Do you have
an SMTP server assigned to this IP address? If you're using the default
SMTP server that is installed with IIS, it probably doesn't have a specific
IP address assigned to it.

Besides all of this, if you're using IIS, it is best to use localhost
(127.0.0.1) as your SMTP server. Try using this and see what happens.

Hope this helps!

Thanks Christopher,

10.34.45.135 is a Pop3 / SMTP server (not Windows)

I can send using 10.34.45.135 in Outlook 2003 and it doesn't need
authentication.

I am not getting any security messages on the Mail server either so I cannot
confirm it is even communicating with the mail server.

I also have a VB.Net 2003 application running on another machine using the
same SMTP server address and this works ok.

Any further help would be appreciated.
