Question

SMTP Problems? Microsoft Exchange

Asked by: Ellmb122

Hello,

I set up the following script on my dedicated server running Windows 2003 Server. It's using ASP and JMail and it runs as a VBS file:

============================

set msg = CreateObject("JMail.Message")
msg.ContentType = "text/plain"
msg.From = "test@mydomain.co.uk"
msg.AddRecipient "test2@mydomain.co.uk"
msg.Subject = "Test Message Subject"
msg.Body = "Test Message Body"

msg.Send(Server1) 'The name of my dedicated server and the domain listed under the Defaul Virtual SMTP Server in IIS.
msg.Close

============================

This works fine, I am now trying to move the script over to a server in my office using Windows Small Business Server 2003 with Microsoft Exchange. This is where I hit a problem.

In theory, the only line I needed to change is the second to last line of the script, the one that refers to the servername. However, because I'm running Microsoft Exchange there is no Default Virtual SMTP Server listed in IIS. I've tried changing this to sbs2003 (the name of my office server) or mynetwork (the name of the office domain) or sbs2003.mynetwork.local, mynetwork.local but none of these work.

I receive the same error every time:

"jmail.Message: The message was undeliverable. All servers failed to receive the message"

It is as if Exchange is blocking the e-mail being sent (although it doesn't appear in the BadMail directory) but I can't see why. Exchange should allow the email to go through because I'm running the VBS file as an administrator on the same machine.

I don't think it's a problem with JMail because I've had a similar problem when using other mail scripts. I have been able to send the mail using CDO because no SMTP server is needed but I need to send it through JMAIL because of the other features I plan to use.

I've looked through the Internet for the last couple of days, I've found other people with similar problems and tried various ASP solutions but I think it's something to do with Exchange.

Need your help experts!

Ell.

First, the SMTP Virtual Server is not missing, its just that when Exchange is installed the SMTP virtual server administration is removed from IIS Admin and moved to Exchange System Manager.  As far as the name of the server, whatever the internal FQDN is (sbs2003.mynetwork.local) should work fine.  However, the caveat with Exchange 2003 is that out of the box, the only users allowed to relay off of the SMTP VS are the ones that authenticate first.  If JMail doesn't contain a method to authenticate the user with the SMTP server, and the script is running on the local box, just add the local servers IP address to the allowed to relay list.  To do this:

- Launch Exchange System Manager
- Browse to Servers, protocols, SMTP, right click on SMTP virtual server and go to properties
- Second tab, click the relay button.  Add the IP address here and ensure "only the list below" is selected

I would not suggest setting it to "all except the list below" as that will open you up to relay.

Hello,

It was all down to McAfee AV blocking scripts from sending mail through the port. It was misinterpreting my script as a mass mailing worm! I've sorted it out now. You will receive the points, thank you for your suggestion.
