Chat Eating Messages (Spam Filter?)

While I realise the game's spam filter exists for a good reason .. it also periodically eats messages, especially for those of us tend to write longer ones most often: IE, roleplayers.

This wouldn't be so bothersome, except the client gives no warning as such - the sender still sees the message echo'd in their own chat history as if it had been successfully sent resulting in a great deal of standing around wondering if the other person you're playing with's dropped dead or something. >.>

Is there some way we could be warned when our message has failed to send, thus? Be it not seeing it ourselves (so seeing the same as other players), or getting an error or some kind of popup warning or.. well.
