Hi Guys,

I found a Thread who helped me out: Cpanel rejecting .eml attachments

In future Cpanel updates, /etc/cpanel_exim_system_filter may get overwritten if you edit it.


1. cp /etc/cpanel_exim_system_filter /etc/cpanel_exim_system_filter_custom

2. Then edit /etc/cpanel_exim_system_filter_custom and remove the eml| from the four noncommented lines that reference it.

3. Then log into WHM, click on Exim Configuration Editor, and change the system filter at the bottom from /etc/cpanel_exim_system_filter to /etc/cpanel_exim_system_filter_custom . Save the changes

Now Cpanel will use /etc/cpanel_exim_system_filter_custom, which if properly edited to remove the 'eml|' references in the particular lines will allow EML attachments to go through in the future.


If Cpanel updates /etc/cpanel_exim_system_filter, you won't benefit from the changes.
