We are on Forms 10.1

On the Web server in the Web Forms configuration > Email Settings the SMTP server is set to our mail server, Port is set to 25, do not have any values for username/password and have a value in the Sender's email account.

When I enter my email address in the Validation and click test, I receive the test email.

When I submit the form from the internal forms server, the email notification goes through. When I try it going through the web portal, regardless whether it is a public or restricted form, the process gets suspended at the email notification task. The "save to repository" task works fine each time.

I've attached the error log.

The reason I'm using an actual workflow to send the email notification is because the notification will be going to an Outlook email group and everyone in the group will access Laserfiche using the same generic sign on to access the submissions. I didn't see how to set this up using the email service task in the form process. However, this is not causing the issue because there is another form process that uses the email service task and it has the same issues.

What happens is when these forms are submitted from the "outside" using the web portal, and it doesn't matter whether they are public or restricted forms, the processes always suspends at the email notifications, either workflow or email service task. If I remote desktop into our web portal web server that is in the DMZ and open forms as localhost and retry the suspended instance it will again suspend at the notification. However, if I remote into our internal forms server and open forms as localhost, when I retry the same instance I tried on the web server the process will complete, sending the email notification.

The settings appear to be correct because I do receive the test email when I try it from both servers. I've had our network & exchange admins look to see if there is any traffic from the web portal web server that might be accessing ports that we have closed off but they don't see anything.

We are just beginning to bring forms/workflow online with our processes so we're not familiar with the whole setup. Any thoughts/suggestions are appreciated.
