Why am I getting recipient maps checked when that IP is listed in mynetworks?

Hello Everyone,
I need help in trying to figure out why I am still
getting snagged by the "check_recipient_maps"
restriction in smtpd_recipient_restrictions. The IP I
am connecting from is listed in mynetworks. As you
can see in "helo" and "mail from", I can get away with
invalid domain and non-FQDN addresses. However, when
I specified an email address to the testing.com domain
that is not on the relay_recipient_maps list, I got
stopped. If anyone can shed some light into this,
I'd really appreciate it. Thank you.

postfix version 2.1.4
