Yes i just found the exim manual today, and you're right there is a directive that must be changed in the exim configuration manager, I've found it I'm just a little reluctant to change it without getting confirmation about what exactly should go there. I'll post on the cpanel forums.
this is helpful thank you.
ok so i should use the same cert that i've already received, that helps. i'll know what to ask on cpanel forums. hopefully someone else will chime in here. i'll change the mx record.
