SMTP not working

I recently purchased Firewall Analyzer. I am trying to setup the mail server settings so that reports can be automatically emailed out.

I can send mail from this same machine through Outlook Express, so I know the ports are open, etc.

When I put in the Mail Server and then try to test it, I get the following error:

Failed :Sending failed; nested exception is: class javax.mail.MessagingException: Could not connect to SMTP host: DEVPDMTS1, port: 25; nested exception is: java.net.SocketException: Software caused connection abort: connect

The firewall Analyzer is installed as a service on a winXP SP2 box.

Help!
