Configuring IIS SMTP for System.Net.Mail

[daokfella]

I'm having trouble using localhost to test the e-mail functions in my
application. I keep getting the following error when sending mail:

"Unable to read data from the transport connection: An existing
connection was forcibly closed by the remote host."

This is what I have in my config:

<system.net>
<mailSettings>
<smtp from="(e-mail address removed)">
<network host="localhost" password="" userName="" port="25"
defaultCredentials="true" />
</smtp>
</mailSettings>
</system.net>

This is my code to send mail:

Dim msg As New System.Net.Mail.MailMessage(_from, _to,
_subject, _body)
msg.IsBodyHtml = True
Dim client As New Net.Mail.SmtpClient
client.Send(msg)

I get the error on the Send method. Anybody have any ideas? I'm
guessing is something to do with IIS. I had no problems with
System.Web.Mail, but I'm trying to use the new System.Net.Mail in my
2.0 app without any luck.

I was able to get things working using an SMTP server other than my
localhost as long as I was sending mail to the same domain. I couldn't
quite figure out the credentials part yet, so I thought I'd stick with
localhost for the time being. Any ideas?

Thanks,

Jason

Is the SMTP service started on the localhost?

1. Do you have an smtp server configured on that computer ?

2. If you do, try setting up a domain alias for it ( Use the IIS Manager for that... )

You can use your machine's name as a domain alias.
