Issue: The ESME attempted to send a message to a distribution list but does not have permission to do so.
How to Solve It?
- Check if the SMSC supports sending messages to distribution lists.
- Verify that the ESME has the necessary permissions to send to a DL.
- Ensure the distribution list name is valid and correctly formatted.
- Contact the SMSC provider to enable or configure DL support.
- Consider sending individual messages instead of using a distribution list.
If the issue persists, consult the SMSC provider for further troubleshooting and configuration adjustments.
