The tutorials on email relay are all pretty old. Just wondering if we should use the tut's for the servers we are building today like the ubuntu 12.10 with ispconfig 3?
Also, because I did follow one of the tut's and restarted postfix, this is what I get:
/usr/sbin/postconf: warning: /etc/postfix/master.cf: unused parameter: smtpd_bind_address=127.0.0.1
It shows 20 to 30 lines of this same messages.
