I have a LAN behind a firewall with port 25 forwarded to machine running
postfix. That machine sends email on to
a Domino server. However, I am using a VM for testing and I cannot change
the forwarded port. So I am doing it
all from the postfix machine. I use the command below to send an email to
an unknown user (from command line).
But it delivers it to Domino anyway. I have only one user defined in
/etc/postfix/aliases file. Do I have the right
configuration to reject unknown users? If not, what am I missing?
Thank you,
Durwin
