hello,

I am trying to send a command line mail message from a server in my iRedMail subnet to the iRedMail server. I get an 503 authentication error. See below. Both the servers are brand new installs of Centos 6.7.

I read to turn on smtp sasl auth.. I have this placed these following commands into main.cf, but I keep getting 503 error. 

Any suggestions on how to make this work?  I can send this exact same message on the iRedMail server and it works.

thank you

in the sending server's /etc/mail.rc file, I have placed something like this-

set smtp=smtp://mail.mydomain.com:25
set smtp-auth=login
set smtp-auth-user=mail.mydomain.com:25
set smtp-auth-password=my_passwd
