You're trying to start opendkim when either:

a) It's already running, or
b) Something else is already running using localhost port 8891.

You have it set to auto-restart, possibly without bound.

Yes, that should be fine. If you still can't restart it and get the same
error, you need to configure it for a port that's not in use by something
else.

The "netstat" and "lsof" system tools might be able to help you figure out
what's already using that port.
