Momentan läuft amavis bei mir als content_filter, ich würde aber gerne emails von aussen per smtpd_proxy_filter und alles was von der shell kommt per content_filter filtern lassen.

Ich würde jetzt aus der main.cf folgendes entfernen:

Code:
 content_filter = amavis:[127.0.0.1]:10024


und in der master.cf folgendes löschen

Code:
        -o content_filter=

und diese zeilen hinzufügen:

Code:
	-o smtpd_proxy_filter=127.0.0.1:10024
sowie
Code:
pickup	fifo	n	-	n	60	1	pickup
	-o content_filter=smtp:127.0.0.1:10024

funktioniert das so?

Vielen Dank
