In Postfix 3.7, the manpage says:
-n Show only configuration parameters that have explicit name=value
settings in main.cf. Specify -nf to fold long lines for human
readability (Postfix 2.9 and later). To show settings that dif-
fer from built-in defaults only, use the following bash syntax:
LANG=C comm -23 <(postconf -n) <(postconf -d)
Replace "-23" with "-12" to show settings that duplicate
built-in defaults.
This also on-line at www.postfix.org.
