I'm trying to use authentication with the Courier ESMTP to allow relaying.
I'm using Courier 0.39.3 on RedHat Linux. The client is Microsoft Outlook
My SMTP access list just contains the localhost and the private network
examples, since I understand that authenticated ESMTP will override this
Delivering mail locally is fine, but if I try to relay through my courier
server to an external mail address I get a "Relay Denied" error and this in
the log file:
oo.com>: 513 Relaying denied
What am I doing wrong? Any help much appreciated.
Lookout may not have the brain cells to know how to do LOGIN or CRAM-MD5.
