The Exim cheat sheet, common commands to manage Exim
Exim is the default email program for all cPanel VPS servers and cPanel dedicated servers. Our Exim cheat sheet will help you manage Exim. cPanel servers where you or your customers have old versions of content management systems like WordPress its possible people can take advantage of these old versions and in turn gain access to your account. Usually, we find accounts are compromised by outdated plugins and themes. Once compromised sites will send mass amounts of spam from your account resulting in the affected account being restricted.
These mass emails cause a huge issue with Exim and the servers load. As the queue gets longer it takes longer to process the emails after a few days the email queue can be tens of thousands of emails long. To manage the queue you can use our Exim cheat sheet.
