ok, but I don't have any content_filter rules in the main.cf file created by ispconfig3 install… and in the master.cf it just says :
127.0.0.1:10025 inet n - - - - smtpd
i've putted "content_filter = amavis:[127.0.0.1]:10024" in main.cf is it ok ?
then amavis restart
it seems to work, but amavis said "file not found /etc/mailname"
anyway, thank you so much for the content_filter information !
