That may not be dovecot but sendmail.
Try fiddling with your sendmail.mc - the lines below are all in there:
dnl #
dnl # Rudimentary information on creating certificates for sendmail TLS:
dnl # make -C /usr/share/ssl/certs usage
dnl #
define(`confCACERT_PATH',`/usr/share/ssl/certs')
define(`confCACERT',`/usr/share/ssl/certs/ca-bundle.crt')
define(`confSERVER_CERT',`/usr/share/ssl/certs/sendmail.pem')
define(`confSERVER_KEY',`/usr/share/ssl/certs/sendmail.pem')
Remember to backup your mc/cf before doing a "make" in case they aren't in sync.
