Scheduled adjustment of mail daemons
Needs Feedback
It would be nice to have a feature in cPanel to adjust [mail] daemons based on schedule (hours of the day/days of the week).
Let's say i want to lower their number in the week-end and after hours in order to give more resources for backups, maintenance, upgrades etc... While I want to increase them during working days/hours to accommodate increasing requests.
An alternative approach would be to auto-adjust the number based on stats.
I like this idea

The concept of attempting to strictly limit/prioritize specific daemons is a very complex process to consider. This seems like the box itself might be overloaded if it's not able to accommodate. I would recommend attempting to bring the box back into a performant state by leveraging features like CloudLinux to resource cap heavy users and allow all daemons to run well at all times. The worry I have, and I think other administrators would have, would be that customers would have a perception that their services are being capped/impacted for "no reason" or that the server is "broken" by not understanding these proposed schedules. What if I'm a customer who almost never sends mail? I imagine they'd be frustrated, too. I'd like to hear more feedback on this.
