Staff member
The default size of email attachment in cpanel is 50MB, but if you want to change this then you can follow below steps:
  • Login to WHM.
  • Click on “Exim Configuration Manager” under “Service Configuration”.
  • Here click on “Advanced Editor” to making changes.
  • You will find “Add additional Configuration Setting” option after scrolling, click on it.
  • Choose “message_size_limit” option and enter the required value.
  • Click on “Save”.
Most of the operators does not allow larger limit, even they allow minimum limit like 10MB or 20MB. But if you have set limit to 100 MB and receiver server has limit of 20MB then attachment will not send.
