How do we set up our IIS 5 (W2K SP4) internal web server's SMTP service to
send mail successfully to our internal Exchange 2003 server?

Our internal web server has ASP forms for employees to fill out (i.e.
vacation). The employee's Exchange email address gets inserted into the From
field, and an Exchange 2003 distribution list is inserted in the To field. I
believe the ASP pages use CDONTS script to send the mail. We have an MX
record set up correctly in our local DNS for the Exchange server. We get
Event 4000 on the web server:

Message delivery to the remote domain '<our mail domain>' failed for the
following reason: The connection was dropped by the remote host.

It sounds like Exchange is dropping the connection because it sees it as
relaying.

Any info would be great. I can't seem to find any docs to help with this.

Thanks,
Joan

The first thing I'd do is use CDO instead of CDONTS and use the
Exchange Server to send email. Beyond that, check the Exchange logs
for the Exchange Server side of the connection and try asking uin an
Exchange group.

Hi Jeff,

Thanks! I think that did it.

There were no errors on the E2K3 server, and the web server spat out error
4.4.7 but the E2K3 server was always up, which made the issue difficult to
understand and tshoot. But using CDO and the E2K3 server directly instead of
using the web server's SMTP service seems to be working.

Joan
