Perfect Server, Ubuntu 12.04 LTS (64bit) Just wondering if this can cause "discombubaration" in postfix. There is a warning message: /usr/sbin/postconf: warning: /etc/postfix/master.cf: unused parameter: smtpd_bind_address=127.0.0.1 Is that something to be concerned or is it OK to simply comment the line in master.cf e.g. # -o smtpd_bind_address=127.0.0.1 since it is apparently not used for anything?
