Steps to reproduce:

1. Set up an SMTP-only email connection for WebCenter as per the following note:
   Note 1182383.1 - How To Create a SMTP Only Mail Connection?
   
   Specifically:
   
   a. From WLST create the External Application and Mail connection with the following commands:
   
   
   b. Restart Spaces.
   c. Add the 2 properties in the Space Custom Attributes as suggested by the note.
   d. Test sending an email from a page, you may have to save the username and password for the first time.
       Make sure that you receive the email correctly, which confirms that sending email works fine from WebCenter.
2. Set up the Notification setting in Application Configuration in EM to point to the new Mail connection.
3. Register a new user with an email address that you can verify.
4. Login with the newly created user.
5. Click on Preferences.
6. Click on Subscriptions.
7. Check all check boxes on the General Subscriptions tab.
8. As an administrator, add the user to the Space that you used in step 1.
   Notice that you do not receive the email, and the above exception in WC_Spaces-diagnostic.log, shows up.
9. Change the Email connection in EM to point to an invalid IMAP host and port.
10. Restart Spaces.
11. Test notification again by adding or removing the user to/from the Space.
    You will still not receive the email, and you will see an exception complaining about IMAP connection not being valid, see above.
12. Change the Email connection in EM to point to a valid IMAP host and port.
13. Restart Spaces.
14. Test the notification again
    Notice that this time the email gets sent.
