# Normally, exim4 looks for certificate and key in different files:
#   MAIN_TLS_CERTIFICATE - path to certificate file,
#                          CONFDIR/exim.crt if unset
#   MAIN_TLS_PRIVATEKEY  - path to private key file
#                          CONFDIR/exim.key if unset
# You can also configure exim to look for certificate and key in the
# same file, set MAIN_TLS_CERTKEY to that file to enable. This takes
# precedence over all other settings regarding certificate and key file.
