c'è solo questo:
# Begin /etc/syslog.conf

#Log to a syslog server

#*.* @192.168.0.1
*.* /var/log/messages

# End /etc/syslog.conf


ho guardato in /var/log/messages e dice:
Nov 12 12:28:06 Yoper postfix/master[9362]: warning: process /usr/lib/postfix/trivial-rewrite pid 2522 exit status 1
Nov 12 12:28:06 Yoper postfix/master[9362]: warning: /usr/lib/postfix/trivial-rewrite: bad command startup -- throttling

e non capisco cosa voglia dire..
