Sounds like a design flaw on their part. If you are seeing an error as indicated, the code isn't set up to handle exceptions very well and it's outputting the uncaught error. WHY it's happening is anybody's guess. SMTP mailers are always fun but have always been reliant on other endpoints for relay. Something could be happening upstream which throws the error, exits the recovery method and leaves you stuck.
Hope you get it resolved
