  1. No, there isn't any configuration parameter for that. Neither is there any possible need to change it.

    You should read What you need to know about Postfix logging?. By default Postfix lets syslogd do the job.

    Postfix daemon processes run in the background, and log problems and normal activity to the syslog daemon. The syslogd process sorts events by class and severity, and appends them to logfiles.

    The /var/spool/postfix/dev/log is only needed if you run Postfix chrooted:

    Note that a chrooted daemon resolves all filenames relative to the Postfix queue directory (/var/spool/postfix).

    Additionally, you almost certainly need to configure syslogd so that it listens on a socket inside the Postfix queue directory. Examples of syslogd command line options that achieve this for specific systems:

    • FreeBSD: syslogd -l /var/spool/postfix/var/run/log
    • Linux, OpenBSD: syslogd -a /var/spool/postfix/dev/log

    The queue directory can be changed:

    queue_directory (default: see postconf -d output)

    The location of the Postfix top-level queue directory. This is the root directory of Postfix daemon processes that run chrooted.
