I mean such address: none@phys.msu.ru, and phys.msu.ru - is local domain of my server. How can I configure Courier to accept such messages?

Create the file .courier-default in your courier aliasdir directory (usually /etc/courier/aliasdir or /usr/lib/courier/etc/aliasdir) and then put the following line in it:

| echo "User $RECIPIENT is unknown"; exit 77

Now any mail to non-existent users of domains on your server will be accepted initially but then rejected with the message "User <recipient's email address> is unknown" and a delivery failure notice sent back to the sender.

Again, if this machine is connected to the internet then you risk begin seriously spammed.

And being blacklisted for irresponsible backscatter. Don't do it, it's not just your problem to deal with anymore...
