Cpanel has announced a few changes that will increase the perfomance of Round Cube, dealing with a growing number of reports regarding excessive CPU usage. The changes have been applied to the Beta Build. And Cpanel will publish these changes to the Edge Build soon.
Round Cube is a very attractive webmail software, due to it’s AJAX features. I hope they can optimize it’s resource usage. You can’t rely on a webmail software that undermines the server’s perfomance.
As you know, you can limit the number of emails any account can send, per hour, in WHM. Just click Tweak Settins, below Server Configuration. But, how do you assign a different value for an individual account, different fro the value assigned to everyother account? You might want to give a certain account a greater limit. Or even restrict that account’s hability to send emails.
SSH to your server. And open the file /var/cpanel/maxemails. Then just add the code:
domain.com=100
This value will override the default value for this domain. So, if you assigned a 2000 limit in Tweak Settings, domain.com would have a limit of 100.
