In order to guarantee you stable and secure e-mail traffic, the maximum number of e-mails per mailbox and hour must be limited. This protective mechanism prevents the server's IP address from ending up on an IP blocklist if spam is sent from an address. The sending limit per hour can be temporarily increased for 24 hours at a time.
To do this, click on Increase Mail Limit Rate. Now set the rate to the wanted number. Note that these rates depend on your hosting subscription. Complete the changes by clicking on Save.
