Assuming you have a single/small list of domains, in filter_recipient:
$LocalRelayAddrs{"192.168.78.2"} = 1; # me!
$LocalRelayAddrs{"127.0.0.1"} = 1;
my $mysender=lc($sender);
$mysender=~ s/[<>]//g;
my $myrecip=lc($recipient);
$myrecip =~ s/[<>]//g;
if (
($mysender=~ /mydomain.com$/i) &&
($myrecip =~ /mydomain.com$/i) &&
(! exists $LocalRelayAddrs{$ip})
)
{
action_notify_administrator("Message-id: $MsgID\nSender:
$sender\nRecipient: $recipient\nAddress: $ip\nHostname:
$hostname\nHelo: $helo\n\nBounced because an external party
claims to be us\n");
# can't use graphdefang_log here...
md_syslog('info', "MDLOG,$MsgID,Spoof,0,$ip,$sender,$recipient,?");
return("BOUNCE","You are not one of our users, so you can't send as
us!");
}
Best Wishes,
Paul.
