system.net.mail vs CDO.message

Question

Hi,

We're migrating from windows 2003 to 2008 32bits (not R2)

and we facing problems sending mails from a winform app.

I've setup a simple vbscript in order to test and a console app as well.

everything goes well while seding emails using the vbsccript (CDO.message) but failed when using the console app (using the System.Net.Mail namespace)

i run both as the same user account, targeting the same smtp server with the same credentials on the same smtp port.

Any idea?

What is the error message you get? Give more details.

Answer 2

The returned error is the following one: "Unable to connecet to remote server" "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"

Answer 3

I've installed Windows Live Mail on the server and i configured the mail account.

No mail can be sent either. i guessing there a configuration problem somewhere.

All firewall settings seems ok since i'm able to sent mail using the vbscript.

any help would be appreciated
