Thank you. However, for some reason this is generating an error:
2018-09-25 14:53:15 1g4jHp-000B76-VQ signing_init: error:0906D06C:PEM
routines:PEM_read_bio:no start line
2018-09-25 14:53:15 1g4jHp-000B76-VQ DKIM: signing failed: PRIVKEY
2018-09-25 14:53:15 1g4jHp-000B76-VQ DKIM: message could not be signed, and
dkim_strict is set. Deferring message delivery.
