The "reject_invalid_hostname" restriction is a legacy alias for
"reject_invalid_helo_hostname", no need to do it twice.

Have you checked your logs???
http://www.postfix.org/DEBUG_README.html#logging
In addition to any warnings, etc, what is logged when a client is
not permitted? Note that returning "OK" in "helo" restrictions
DOES NOT short-cut "sender", "recipient" or "data" restrictions.
