Sending Limits

Sending Limits (/emails/send-limits) shows how much outbound mail each of your mailboxes has sent in the last hour and what its limit is.

You can tighten a mailbox's limit. You cannot loosen it past the ceiling already set for you: that is whichever is smaller of your hosting plan's cap and the server-wide default. A limit you could raise without bound would not be a limit.

Lowering one is worth doing when you know a mailbox only ever sends a handful of messages a day — a much lower number notices a stolen password sooner than the plan's own figure would.

The counting, the suspension and the alert all happen in a cron job, driven by hitechcloudcli email-sendlimit; this page reads and writes what that command owns.
