emails not sending

[Gandi]

yesterday evening my emails stopped sending with error code "too many recipients". I reduced it to one recipient but it still says "too many recipients"

Hi @Gandi 

The spam protection has been triggered to temporarily stop the sending from the mailbox.

What TT error code did you see? A TT501 error means the rate limit will be relaxed in an hour. Other codes may impose a rate limit for up to 24 hours.

It depends on what caused the sending limit to be exceeded.

Sending to a lot of recipients would trigger a temporary stop. Actual or suspected unauthorised use would trigger a lower limit that even normal use would trigger.
