It's using DNS....

OK so this was supposed to match
[10.0.0.207]:25 without status=
[10.0.0.208]:25 without status=
(that's why there were two dots in the pattern).
If there are no such records, then the Postfix SMTP client
does not connect to one box after having tried the other first.
To find out why random DNS is not working, we need verbose logging
# postconf -e debug_peer_list=10.0.0.207 debug_peer_level=1
