I'd like to request a feature where we can limit the amount of emails sent out by 1 user. Competitor DirectAdmin has this feature and it works very well.
The reason for this request is now with mobile devices everywhere, almost all our users use our Plesk server as their SMTP server. From time to time login credentials get stolen, guessed or otherwise fall into wrong hands.
When this happends our Plesk machine is used to sent out tens of thousands of spam messages, which in turn causes our IP to get blacklisted.
It would be great if we could limit the amount of outgoing messages per mailbox. This would limit the spam outbreak to a very small fraction of the amounts we're seeing now.
