Why do you think it would be more secure? It's still readable by the exim
user.

BTW, by configuration contains:

CERTS    = /opt/dist/certs
DB    = /opt/exim/etc/db


PARAM    = ${lookup {$interface_address} cdb {DB/addrparams.cdb} }
NAME    = ${extract {name}{PARAM} {$value} {localhost} }


tls_certificate    = CERTS/server/NAME


(On reflection, my earlier suggestion of trying to restrict the
certificate readability to root is not sufficient, because a copy of it
would be available in running copies of Exim, recoverabe by any code
running as the exim user.)
