Exim rule to deny spoofed senders

[justjaph]

Hi.

I'd like to add something like:

deny
message = The sender name must be the same as the login id
condition = ${if eq{${domain:$sender_address}}{${domain:$authenticated_id}}{no}{yes}}

to the exim rules: any hint on where to add it and the correct syntax ?

Regards,

/usr/local/cpanel/etc/exim/sysfilter/options/cpanel_exim_system_filter
