Yes, you have to permit SMTP (port 25) truogh the firewall (DMZ) , and if

you have put in a smarthost you has to permit SMTP to that server from the

DMZ!

=C4mne: [asp_cdo] RE: CDONTS not sending messages...





I have the same problem. When I moved the script to production server (the

webserver in DMZ zone), and I can't send the mail. It run perfectly on my

development server.

Anything to do with firewall?

I have check the queue/badmail but no mail in side.

	They might not be sent...check the queue and badmail folder.

	Is there a firewall?

	Are you trying to send email to Internet or back to internal LAN?

	Is DNS accessible for that server?

	If not, specify a smart host, who does have DNS service accessible.

	Hi Folks,



	I've just moved my application which uses CDONTS to a production

server 	(on

	the DMZ rather than on our network), and the messages are not

getting sent.

	I have verified that the messages are being created properly by =3D

	stopping the

	default SMTP site and sseing that sure enough the messages do build

up

	in the pickup directory.  Starting the site again results in the

messages

	disappearing, hence they are being sent, although they are not

arriving at

	their destinations.



	Clearly this means that the SMTP service has not been configured

	correctly.

	As our support people don't have much experience of this sort of

thing, 	can

	anyone tell me how to configure the SMTP service with the correct

mail gateway?

Can you expand on this?  Exactly what should I be telling the support 

guys

to do?



We have an Exchange server inside the firewall which sends messages to 

the

outside world, presumably through some kind of gateway in the DMZ.  The 

web

server resides in the DMZ.  Can the SMTP service of the web server send

messages directly to the mail gateway, or do the messages have to come 

back

though the firewall to the exchange server?



(As a developer I expect this stuff to just work, but when the support 

guys

don't know how to fix it, what else can I do except try to find out for

myself?)
