Postfix was correct to bounce the mail, since you told it to use
outputs.orbs.org and outputs.orbs.org listed that mail server.
I just checked and it looks like it has been de-listed since then.
This is always a risk when using reject_maps_rbl -- you may lose
legitimate mail.

(looks like you had some copy/paste problems above...)
Options:
- do nothing and accept the fact that using maps_rbl_domains may
reject legitimate mail.
- don't use outputs.orbs.org
- make a special exception for 216.136.174.40 by...
smtpd_client_restrictions =
permit_mynetworks
hash:/etc/postfix/maps_rbl_exceptions
reject_maps_rbl
Then create /etc/postfix/maps_rbl_exceptions with this line in it:
216.136.174.40 OK
Then run 'postmap /etc/postfix/maps_rbl_exceptions'
Then run 'postfix reload'
