How to set email attachment size limit to 5MB

Hello Sobhi, Thanks for posting your question on how to change the attachment size limit to 5MB per email. This can be done through WHM as the root user. Once logged in you will navigate to the Exim Configuration Manager > Advanced Editor tab. Then scroll down to the middle of the page to find the Add additional configuration setting button. Then click on it and enter: message_size_limit into the field that appears. Then you can use the 5 value. Scroll all the way down to the bottom of the page and click Save and that should do it! I hope this helps. Sincerely, Carlos D.
