Sure, sorry for being unclear. In short, when snoopy is installed, nullmailer is not working. Here is an example to illustrate: (apt-get install nullmailer) normal functioning: [EMAIL PROTECTED]:~> mail [EMAIL PROTECTED] Subject: test testing . Cc: [EMAIL PROTECTED]:~> sudo su host:/home/alfs# mailq host:/home/alfs# find /var/spool/nullmailer/queue/ /var/spool/nullmailer/queue/ host:/home/alfs# (Nothing is in the queue, since the mail has been delivered.
