I have a client with a limit of 20 mails per hour (sent) I updated the limit to 300 (domain and subscription also) but it does not work, see the capture, as you can see the limit is 300 but he can only send 20. I changed 300 to 200 or 50 but it is the same...
Yes, all leves are set at 300, mailbox, domain and subscription. Also I set 300 mails manually to this mailbox (instead of the general limitation, 300 too) but it does not work,
