what i must put in setgid_group:?
check your postfix config file to make sure it has a value in the setgid_group field.
Check that the setgid_group parameter is non-empty in main.cf. grep setgid_group /etc/postfix/main.cf postconf | grep setgid_group
just comment out the line setgid_group in the file /etc/postfix/main.cf This should get the error away
setgid_group = postdrop
bad string length 0 < 1: setgid_group
