External database vs /etc/postfix/mysql-virtual_outgoing_bcc.cf
Hi, I use Ubuntu 16.04 & latest version of ispconfig 3.1.1p1 and setup by https://www.howtoforge.com/tutorial/perfect-server-ubuntu-16.04-with-apache-php-myqsl-pureftpd-bind-postfix-doveot-and-ispconfig .
I use external db which works properly until postfix configuration. There is bunch of related mysql files in /etc/postifx/mysql-* but just "/etc/postfix/mysql-virtual_outgoing_bcc.cf" is not updated external IP but by 127.0.0.1 .
This cause error: Temporary MTA failure on relaying, from MTA(smtp:[127.0.0.1]:10025): 451 4.3.0 Error: queue file write error (in reply to end of DATA command))
Not sure if it your problem but it is definitely related to this project:)
Big thanks for your work, Pavel
