[Dovecot] wrong config file?

[Phil Howard]

The sample provided config file (the one I started with by editing it)
included the following text:

# ------------------------------ WARNING -------------------------------
>
> # If there's a file /etc/dovecot/dovecot-postfix.conf, which is part of
> # dovecot-postfix package, it will be used instead of dovecot.conf.
>
> # Keep in mind that, if that file exist, none of the changes in
> # /etc/dovecot/dovecot.conf will have effect on dovecot's configuration.
> # In that case you should customize /etc/dovecot/dovecot-postfix.conf.
>
> # ------------------------------ WARNING -------------------------------
>

So I expected it would use that by default.  It seems to not be doing so.
Does this mean I have to modify the startup scripts to add the -c option to
force the use of this config file?  Or should I just put all my configs in
the default "/etc/dovecot/dovecot.conf" file?

When doing "dovecot -n" it became apparent that my configs were not being
used.  But "dovecot -c /etc/dovecot/dovecot-postfix.conf -n" was doing it.
Any idea why it's not behaving as those comments described?
