Postfix logs its activities at different levels of severity. The
worst one can do is to split the Postfix event stream into different
files for different levels, such that one file contains only normal
activity, one file contains only warnings, etc.
In such a setting, a warning/error/fatal/panic message loses much
of its value (for you or people who can help on the postfix-users
list) because it lacks the context of normal activity that immediately
precedes or follows.
On the other hand, Postfix can produce a lot of logging on a busy
server, therefore logging the same thing multiple times can be
wasteful. I use one logfile and rotate as often as needed; you may
want to use one logfile that records all severity levels, and one
logfile for warning/error/fatal/panic only.
