Dovecot not changing SSL key and certificate as in config file

[Mitchell McMillan]

I am trying to use my (decrypted) SSL key and certificate in Dovecot. I
have changed /etc/dovecot/conf.d/10-ssl.conf like so:
ssl_cert = </etc/ssl/private/ssl-chain-mail-mydomain.com.pem
ssl_key = </etc/ssl/private/ssl-key-decrypted-mail-mydomain.com.key

However, after running service dovecot restart, dovecot -n still says that
the files /etc/dovecot/dovecot.pem and /etc/dovecot/private/dovecot.pem are
being used.
I am using dovecot 2.2.9, any help would be greatly appreciated.
