Hi Folks,

Getting a lot of mail which is from an unknown host. I.E. postfix produces

grep "connect from unknown" /var/log/mail.log

postfix/smtpd[21643]: connect from unknown[]
postfix/smtpd[23319]: connect from unknown[]

I understand I can add


to postfix but I would like to first see what e-mail I may be losing before I do this. What I would like is to redirect the e-mail when this occurs to a different user account. See whether the change makes sense and then add it to postfix.

My environment is
Ubuntu Server 12.10
