Hi, My .qmail-default have the line: | /var/qmail/bin/fastforward -d /etc/aliases.cdb. The /etc/aliases have the line: MAILER-DAEMON:admin . I'm receiving a lot of emails from someone trying to spam me but, the accounts that the spammer is trying to spam doesn't exists so, the qmail send a MAILER-DAEMON message to 'admin' saying that the account doesn't exists. I disabled this line from .qmail-default in order to prevent the qmail from send this message but, I looked at the logs and I saw that when a message to an unknown arrive this logs the message like DID. My question is : Where this messages to an unknown user is stored ? Is this message discarded ? Roberto Samarone Araujo
