RelayedOpenRelay?

Hi,

I realize this is an FAQ, but I've tried an exhaustive list of changes to
try and solve it and still can't figure out why mail is reported
as RelayedOpenRelay.

I found this thread from more than a decade ago where Mark suggested it was
somehow related to the source IP address matching @mynetworks or
$originating flag set by a policy bank.

My server IP is 209.216.99.115/32. It is included in @mynetworks:

@mynetworks = qw( 127.0.0.0/8 192.168.0.0/16 209.216.99.0/24 );
@client_ipaddr_policy = (
  [qw( 147.135.9.126/32 )] => 'TRUSTED', # polaris
  [qw( 209.216.90.115/32 )] => 'TRUSTED', # xavier
  \@mynetworks => 'MYNETS',
);

ip_trace from my logs does have my IP in it. My logs are stored in JSON
format, so they're a complete mess or I would post it here.

What could I be missing?

Thanks,
Alex
