Error message when sending emails thru PC

Power Church Online
Our secretary is getting this message when sending emails. "550 User secretary@fbctroync.com has exceeded its 24-hour sending limit. Messages to 5 recipients out of 5 allowed have been sent. Relay quota will reset in 23.15 hours."
She has not gotten a message like this before. Can you tell me if this is a Power Church issue/setting or is this something with her email carrier.
Thanks.

Nothing to do with Powerchurch, that is coming from your internet provider/hosting service. If she's never gotten that message previously, I suspect your provider has changed their quota.
