iRedAPD 1.7.0 rejects IPv6 hosts that are listed in MYNETWORKS variable with "Policy rejection not logged in":

$ telnet XXX::166 25
Trying XXX::166...
Connected to XXX::166.
Escape character is '^]'.
220 XXX ESMTP Postfix (Debian/GNU)
HELO YYY
250 YYY
MAIL FROM: aaa@bbb.cc

RCPT TO: aaa@bbb.cc
554 5.7.1 <aaa@bbb.cc>: Recipient address rejected: Policy rejection not logged in
quit
221 2.0.0 Bye

For IPv4 it is working.

$ telnet XXX.166 25

Is there a bug in iRedAPD regarding IPv6 hosts/networks?
