Email notifications in ColorProof

You can enable email notifications for specific events, results, and errors under
System > General > Email System Notifications

For each notification, enter one or more recipient email addresses. Separate multiple addresses with semicolons.

Email delivery methods

To configure the email server used to send notifications, go to System > Remote Proofing. Choose one of the following Email Delivery Method options:

• SMTP Email Server — Use your organization’s SMTP server.
• Microsoft 365 (OAuth2) — Authenticate and send mail through your Microsoft 365 mail server.
• GMG Cloud — Send notifications through GMG Cloud. Recommended for the simplest setup. No email-server configuration is required.

How to configure an SMTP email server

1. Select SMTP Email Server as the delivery method.
2. Enter the required SMTP settings:
   • Sender Email Address
   • SMTP Server Address
   • SMTP Server Port
   • User Name
   • Password
   • Use SSL, if required by your mail server
3. Ensure that Sender Email Address and User Name are identical. Enter the complete email address in the User Name field.
4. If you enable SSL, the SMTP port is commonly 465 rather than 25. Confirm the required port and security method with your IT department.
5. Enter a Test Email Receiver address and click Test to verify the connection.

How to configure Microsoft 365 (OAuth2)

1. Select Microsoft 365 (OAuth2) as the delivery method.
2. Authenticate with your Microsoft account when prompted.
3. Leave the SMTP port set to the default value of 25, unless your IT department provides different settings.
4. Send a test email to verify the configuration.

How to use GMG Cloud for notifications

Just select GMG Cloud as the delivery method.

No additional email-server configuration is required. GMG Cloud sends notifications to the recipients configured under System > General > Email System Notifications.

Troubleshooting: Email notifications are not being sent

If email notifications are not sent, check the following:

• SSL 
When Use SSL is enabled, the mail server must support implicit SSL on the configured port.
If your server supports only STARTTLS/TLS, it may reject the connection. Check the supported encryption method with your mail provider or IT department.

Microsoft describes it as follows:

• Incorrect SMTP port
Some email providers restrict or block specific SMTP ports. Confirm the correct port with your IT department.

Typical settings include:

• SSL: usually port 465

• Microsoft 365 (OAuth2): usually port 25, unless your IT department specifies another port

• Sender address mismatch
The Sender Email Address and User Name must match exactly. Both must contain a valid, complete email address.

• Authentication errors
Verify the following SMTP settings:

• User name and password
• SMTP server address
• SMTP port
• Whether SSL is required
