I just had a problem where I was unable to send a reply to a new request. After typing in my replay and sending it, I got a very generic "Sending notification failed". The email address was OK, I could send from other calls OK, you could even send replys from other calls byu the same person. It seemed to be something unique about this request.
After playing around for a little while, trying to discover the problem, I realised that the only thing "unique" about this call was that the email sent by the requestor that initiated the call was very long. I cut down the length of the reply and then everything worked as it should.
Can I request that this very generic error message be made a little more "friendly"?
