master.cf content_filter=

Mal eine Frage zu den Einträgen in der master.cf, die bei mir beginnt mit:

# smtp   inet  n  -  n  -  -  smtpd -o content_filter=

smtp    inet  n  -   n  -   -  smtpd

Ist das richtig so?


Ich hänge die ganze master.cf noch mal dran. Und auch die main.cf. Ist 
da irgendwas falsches zu entdecken?

postgrey läuft als daemon postgrey --pidfile=/var/run/postgrey.pid 
--daemonize --inet=127.0.0.1:10029 --delay=120 --max-age=20


Für jede Hilfe bin ich dankbar.


Grüße

Christoph
