Auto Messages enables you to send either emails or eBay messages to your buyers.
If the chosen sending method fails, the fallback feature will try and send your message with the other sending service.
Your message is set to send with eBay Messages.
The system tries to send your message, but eBay has an error with their messaging system,

How to enable Fallback for message delivery:
In the Messages tab, edit one of your messages:
On step 2 (Message Service), enable Use fallback.
