Hello Community,
I administer a CUC server, it has stopped sending email notifications, when I do a test, I get the error code 503:
![CUC.png CUC.png](https://community.cisco.com/t5/image/serverpage/image-id/128771iE88F10620BFFA981/image-size/large?v=v2&px=999)
I do the test from: Unified Messaging/Unified messaging Account Status.
Email notifications worked fine before.
Kindly help me resolving this issue.
Best regards.
