The postfix mailing list at www.postfix.org is where I see many knowledgeable
people post. Make sure to follow the instructions in the welcome message on
what to include in your post. You may find useful information about the failed
delivery by doing (as a privileged user):

     postqueue -p

Include this information as well.

The message indicates a rejection by Indra's server. Ask the experts at
postfix.org for help on determining if your postfix successfully authenticated
(your prior test was for a different port, doesn't tell you about port 587).
