Specifying an empty value does not make the parameter go away.
Many parameters can heva an empty value. Some even have it as
the default.
To remove all instances of a parameter:
Before:
/etc/postfix/main.cf:
policy_time_limit = foo
policy_time_limit = bar
Command:
# postconf -# policy_time_limit
After:
/etc/postfix/main.cf:
#policy_time_limit = foo
#policy_time_limit = bar
Wietse
