I'm setting up a courier 0.53 mail server with ldap users. I can't send mail to or from users on this new server. Users should authenticate, and this is functioning as far as the logs tell me. I have the IP of my internal network in esmtpaccess file with "allow, RELAYCLIENT", and as you can see sending user is being accepted.

Unrelated to your problem, I'd note that you don't need to both authenticate *and* specify RELAYCLIENT in the esmtpaccess file. Either one will allow users to relay messages. If you want to make sure that users authenticate, you should remove the RELAYCLIENT settings from esmtpaccess, so that they can't relay unless they AUTH.

Here is the maillog snippet:

Jan 17 11:40:10 njupiter courieresmtpd: RCPT TO:<othe@example2.com.uy> Jan 17 11:40:10 njupiter courieresmtpd: error,relay=client-ip-address,from=<us@example.com.uy>,to=<othe@example2.com.uy>: 400 Service temporarily unavailable.

That error message indicates that there's a problem resolving aliases. Maybe run "makealiases"? If LDAP_ALIAS is set to 1 in /etc/courier/ldapaliasrc, try setting it to 0 and get the rest of your setup tested, before you try to add LDAP aliases to the mix.
