[3.x] Remove "Max emails per hour" settings

If it works as described, I think it's a bug. Of course all entries should be send.

I see three alternative options:
1. Fix the functionality
2. Change the functionality to a digest every X hours. Instead of sending separate mails, send one email with a list of entries. This should be separated as optional submodule.
3. Remove the functionality

I think (1) is the best option, 2 is a possible feature request. 3 should be considered if (1) is hard or the option isn't widely used.

I think, this function is removable.
It is implemented incorrectly and I think it is unnecessary. You should use https://api.drupal.org/api/drupal/core%21core.api.php/group/queue/10 for the correct solution. Anyone who needs a scheduled mailing can use the https://www.drupal.org/project/queue_mail → module.

@nevergone I agree it might be best to remove it and keep the module simple.
If anyone needs it then, it should be added as submodule to not bloat the core features.

Ok, I create a issue fork and start.

Please test and write feedback.

These settings will be properly removed in 🌱 [Meta] 3.x Feature / Concept Improvement issue Active , where we are also fixing some other problems. No need to continue any work in this issue, but we'll still keep it open as a reminder.

Fixed by @LRWebks in the parent issue.

Automatically closed - issue fixed for 2 weeks with no activity.

Ok I think we need something similar sooner or later: ✨ Implement a mass-email-sending protection (frequency capping) Active
Just ran into a case with hundreds of mails triggered by a search engine crawler triggering a lot of error log entries...
