Hello,

Across almost all of our servers, we've ran into an issue where suddenly, emails are bounced back when the customer hasn't completely reached the maximum emails per hour limit. Below is an example of that. Throughout the day (from 1 PM to 5 PM or so), ~1000 emails are sent out per hour. 2000 is the limit on the server. However, even though this goes through fine for most of the hours, during 3 PM, at 3:37 PM, it starts giving back the 2000 emails per hour error (as described below) until 4:00 PM. Is there a file that governs over this? If so, which file is it?

this used to be working fine until the latest cPanel update to 11.25 in December so I'm wondering if its related to any changes made then.

root@pasta [~]# cat /var/log/exim_mainlog | grep ####.net | grep "2010-01-27 14" | grep "<=" | wc -l

root@pasta [~]# cat /var/log/exim_mainlog | grep ####.net | grep "2010-01-27 15" | grep "<=" | wc -l

root@pasta [~]# cat /var/log/exim_mainlog | grep ####.net | grep "2010-01-27 16" | grep "<=" | wc -l
