The TT502 error means that your mail sending has been restricted because of too many outgoing recipients in the last 24 hours. It will take 24 hours for the full sending allowance to be restored. Normally you would be able to send to hundreds of recipients each day.

There are circumstances that can trigger a lower sending limit. Using mail via a non-UK network, a network where the IP address is a non-UK address or using a VPN where the VPN host is outside the UK.

Something about the way or rate your mailbox is sending messages has caused the spam protection process to kick into action.
