1 ) Pagination should be controlled by some whare. Currently, it’s 5 which is very small.
2 ) It should be enabled by default like daily max 500 per email as standard and per domain 10000 or some number. It will help us to fight against spam.
3 ) Real-time email relay monitoring and hourly/daily report with sorting orders.
As I know and have experienced on Shared Hosting using cPanel there is an email limit is 500 Emails/Hour.
So what if using CyberPanel on VPS and how setup it for max limit as you need?
It will be good if we have feature. It will fight against a spammer in case any account gets compromised. Let Admin decide what they want whether 500 or 5000 or unlimited.
