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="noreply@m ytestsite.com">
<network host="localhost " password="" userName="" port="25"
defaultCredenti als="true" />
</smtp>
</mailSettings>
</system.net>

This is my code to send mail:

Dim msg As New System.Net.Mail .MailMessage(_f rom, _to,
_subject, _body)
msg.IsBodyHtml = True
Dim client As New Net.Mail.SmtpCl ient
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?

re:

!localhost as long as I was sending mail to the same domain.

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.
