Email cannot be sent on Web Server running 2003 Server

              I am having a problem with sending emails from our Web Server.  The Web Server is running IIS 6.0 2003 Server and a Web Based Employment Applictoin Software.  A user will input their email Address, and once they have completed a web based form and selected submit, the program sends the applicant an acknowledgement email.  However, they are not receiving the email.
      The SMTP service is running.  I am able to telnet using port 25 to the server, and I am able to telnet using port 25 from the server to another email server such as AOL.
      I am at a loss.  Can anyone provide me some other things I may need to do to get this to work?

Any error indications other than the user not receiving the mail?

Maybe sent but undeliverable?

Can you send yourself a 'test' response?

Are frontpage extensions being used/required?

Any logs indicating a problem?

Is it Wednesday? :-)

Seriously; the problem is too broadly stated to do more than guess.

o      Thanks for the response, and you are correct it is very borad, but I am not very familure with this aspect of IT, but here is an error email:

Delivery to the following recipients has been delayed.

o   A contractor manages the Web based application, and with out going into the application, how eles would I attmepted to send an email using IIS?

o   And I have no log errors, besides a CAL issue that I am dealing with.
Is the SMTP Virtual server pointing to an external DNS server? Delayed does not necessarily indicate a problem in sending. Usually this is related to DNS and an inability to resolve the domain name in the email address. After about three days, it will do something like time out the delivery and then send an NDR. Have you received an NDR yet? This will tell you the specfic problem.

Also, I would make sure that the SMTP virtual server will allow relaying from itself. It sounds strange, but it may work if you allow the IP address of the web server to send email through the SMTP virtual server. I'm assuming that you are using the native SMTP service in W2K3.

frs 50, thanks for your help.

I did not provide all of the errors that I have received and you are correct the email did fail after two days which is the default setting on the Defaul SMTP Virtual Server.  

The serve is pointing to an internal DNS on our intranet.  I have done an nslookup and I get IP resolutions for name
NSLOOKUP response to
Server:  svps-dc1.svpsn.district68

Non-authoritative answer:

HELP:  I am not sure how to determine if the SMTP virtual server will allow relaing form itself.  And yes I am using the native SMTP serveice in 2003 server.
