Sending external mail via asp and CDONTS

I 'm developping a web application which sends an email automaticly. In our network we have a developer server NT4-DEV. Here is the IIS and SMTP server installed. We also got an administration server NT4-ADMI. Here is the exchange server installed. On the SMTP server I fill in for tje domain name: and for the smart host : NT4-ADMI. When my ASP page sends an email to the smtp server all emails are send if I send to an internal email adres (with domain name However if I want to send an e-mail to an external adress(e.g. as domain name) I receive an email from the exchange server with following info :

Your message did not reach some or all of the intended recipients.

  I think the exchange server does not understand the domain address. please install a DNS server and try to connect. Configure the IP of the ISP properly
The code is 100% perfecto.

The fact is this CDONTs has to be working on a machine / system which is directly exposed to the internet.  The advatange of CDONTs is to be able to send HTML based messages with images and stuff like that and be able to view the same intact with OE or MOutlook 2000.

The SMTP Service of IIS at port 25 listens for connections from the outside world..  So they send mails just like that.. no username or no account needs to exist on the machine you sending out mails.

Exchange server has nothing to do with CDONTs the main reason being all the mails if you have tried do not get logged in the sent items when you send, instead you notice all the mails would be exisiting in the queue directory of the Mailroot of IIS. They are not gone anywhere.

I hope this solves your problem. If you need for an intranet then you need to go in for 3rd party tools or do your own CDO collaboration.
