I have put the local domain name into /etc/courier/locals and put a file
contains all the name of this mail server(one per line) under
/etc/courier/esmtppercentrelay.dir. then run /usr/lib/courier/sbin/makeacceptmailfor, at last I restart courier. The situation is: I can send and receive mails(received nothing) but if I send
a mail from other server to a user of this mail server I will get such a error
message:

This is a delivery status notification from NatServer, running the Courier mail server, version 0.37.0.

The original message was received on Mon, 28 Jan 2002 20:26:47 +0800 from email.bnu.edu.cn (email.bnu.edu.cn [202.112.80.130])

Your message to the following recipients cannot be delivered:

I have only one mail server and one MX record for this domain:flyingwebman.com. If I am using sendmail, I know I should put local domain name(flyingwebman.com)
in sendmail.cw file, but with courier, i don't know how to do...
