Hi. I'm trying to configure a dedicated server that runs ASP.NET to send mail through
the local IIS SMTP server but mail is getting stuck in
the Queue folder and doesn't get delivered.
I'm using this code in an .aspx page to test:
<%@ Page Language="C#" AutoEventWireup="true" %>
<% new System.Net.Mail.SmtpClient("localhost").Send("
[email protected]",
"
[email protected]", "testing...", "Hello, world.com"); %>
Then, I added
the following to
the Web.config file:
<system.net>
<mailSettings>
<smtp>
<network host="localhost"/>
</smtp>
</mailSettings>
</system.net>
In
the IIS Manager I've changed
the following in
the properties of
the "Default SMTP Virtual Server".
General: [X] Enable Logging
Access / Authentication: [X] Windows Integrated Authentication
Access / Relay Restrictions: (o) Only
the list below, Granted 127.0.0.1
Delivery / Advanced: Fully qualified domain name = thedomain.com
Finally, I run
the SMTPDiag.exe tool like this:
C:\>smtpdiag.exe
[email protected] [email protected]
Searching for Exchange external DNS settings.
Computer name is THEDOMAIN.
Failed to connect to
the domain controller. Error: 8007054b

I'm using ASP.NET 2.0, Windows 2003 Server and
the IIS that comes with it.
Can you tell me what else to change to fix
the problem?
Thanks

This is a dedicated server that's why I'm installing
the SMTP manually.
EDIT: I use exchange so its a little
different, but its called a smart host
in exchange, but in plain SMTP service
config i think its called something
else. Cant remember exactly
the
setting name.
Thank you for pointing me at
the Smart host
field. Mail is getting delivered now.
In
the Default SMTP Virtual Server properties,
the Delivery tab, click Advanced and fill
the "Smart host"
field with
the address that your provider gives you. In my case (GoDaddy) it was k2smtpout.secureserver.net.
