+> Container support: Postfix 3.3 will run in the foreground with "postfix start-fg". This requires that Postfix multi-instance support is disabled (the default). To collect Postfix syslog information on the container's host, mount the host's /dev/log socket into the container, for example with "docker run -v /dev/log:/dev/log ...other options...", and specify a distinct Postfix syslog_name setting in the container (for example with "postconf syslog_name=the-name-here").
