I have just built up a new server using RHEL4 update 4 and have Courier 0.54.2 
and Courier Authlib 0.59 installed.

The Courier packages were installed using rpmbuild -ta to create rpms and the 
rpm -ivh was used to install Authlib and Courier. rpmbuild was executed as a 
standard user. The rpm install was run as user = root. Defaults were used all 
the way through.

Now I have a problem where everything but inbound mail seems to be working. I 
can run authtest as root and get Authentication succeeded. The Webmail 
interface is working and I can login and send messages from the account. IMAP 
is installed and I can connect with a mail client and see folders created using 
the webmail interface. I can also get to webadmin and change settings.

Again, I can send but can not receive.

I ran testmxlookup against my domain and it returns the correct public IP 
address for the mail server.

/etc/courier/me has my correct domain name in it. The same for the locals and 
defaultdomain files.

If I stop courier then courier-authlib and then restart, I do not see any error 
messages when the modules load:

/etc/init.d/courier-authlib start
Starting Courier authentication services: authdaemond

/etc/init.d/courier start
Starting Courier mail server: courierfilter webmail courierd esmtpd imapd 
imapd-ssl

Checking maillog, I see messages like this:

I also see some messages like this:

Jan 25 20:15:02 srvr courieresmtpd: error,relay=::ffff:72.15.222.65,msg="502

What do I need to do?
