Hello everybody!

I would like to implement DomainsKeys, I found this good tutorial on this website (http://www.iredmail.org/wiki/index.php? … Domainkeys)

In the example I read:

DAEMON_OPTS="$DAEMON_OPTS -b s -c simple -d <domain> -D -h -m ORIGINATING -s /var/lib/dkim/<domain>.pem -S <selector>"

<selector> should be putted in the DNS so I can choose a name....ok, what about adding more than one domain? Do I have to repeat this line ?

Thank you!
