I cannot edit exim.conf because a cPanel update will overwrite it.
I need to change the IP used to send mail, within the Exim Configuration Editor in WHM.
Each time I try, I place the code in the box below:
message_prefix =
message_suffix =
I enter:
interface = ip
I also have tried:
interface=ip
An error displays at each save, "Invalid syntax"
I thought the same thing would be typed as you would type in exim.conf directly.
Does anyone have any advice on this?
