Package: opendkim
Version: 2.11.0~alpha-10+deb9u1
OpenDKIM fails on boot but works fine when restarted manually. First,
let's investigate the state after reboot:
$ systemctl status opendkim
● opendkim.service - OpenDKIM DomainKeys Identified Mail (DKIM) Milter
Loaded: loaded (/lib/systemd/system/opendkim.service; enabled;
vendor preset: enabled)
Active: failed (Result: exit-code) since Sun 2020-09-27 10:18:19

Process: 1001 ExecStart=/usr/sbin/opendkim -x /etc/opendkim.conf
(code=exited, status=78)
/var/log/mail.err and mail.info contains no error messages.
Restarting opendkim manually resolves the problem, leading me to believe
that it is starting too early.
$ systemctl restart opendkim
$ systemctl status opendkim

starting (args: -x /etc/opendkim.conf)
As a permanent fix, I made opendkim start after MariaDB by modifying the
service definition:
$ nano -w /etc/systemd/system/multi-user.target.wants/opendkim.service
I changed
After=network.target nss-lookup.target
to
After=network.target nss-lookup.target mariadb.service
OpenDKIM now starts as expected when rebooting.
