I have a VPS with cPanel and i am running around 400+ email accounts under a Office Network, I don't have STATIC IP but i am facing issue when any 1 of employee forget the password and try to access it too many times so cPanel Blocks the IP and entire Network is unable to get / sent mails due to that employee..
This could have been very easy if I have a STATIC IP and i can put into WhiteList. Currently i have turn the firewall off due to this. Any tips or suggestion would be great
