Blind Copy BCC Outgoing eMail Using Exim

Issue: Client requires outgoing email from a specific account to be blind copied to another account. Server is CentOS based, using cPanel, and Exim.

Solution: Create and edit a custom Exim filter file.

Copy the existing Exim system filter file:

cp /etc/cpanel_exim_system_filter /etc/cpanel_exim_system_filter_custom

Edit /etc/exim.conf.localopts to point to the new file you just created (cpanel_exim_system_filter_custom)

nano /etc/exim.conf.localopts

and change the “systemfilter” parameter to read as:


Add the directives to the new system filter file (cpanel_exim_system_filter_custom)

nano /etc/cpanel_exim_system_filter_custom

and add using the following syntax example below:

if $sender_address_domain is

Change “” to the actual email account that is used to send email..
Change “” to the actual email account that you want the Bcc’d email to be copied (sent) to.

Rebuild Exim:


Restart Exim:

service exim restart

eMail sent by will be blind copied Bcc’d to

Note: If for some reason there is no /etc/exim.conf.local file, then log into WHM >> Exim Configuration Editor >> Advanced Editor and save the file (don’t make any changes). That should create the initial exim.conf.local file
