Every time my postfix restarts I get: Code: /usr/sbin/postconf: warning: /etc/postfix/main.cf: undefined parameter: virtual_mailbox_limit_maps It runs fine, no other problems but what exactly is this error telling me? Couldn't find much with Google but found this how-to by FALKO which shows this exact same error and nobody seems to have questioned it? => https://www.howtoforge.com/perfect-server-ubuntu-13.04-nginx-bind-dovecot-ispconfig-3-p6
