[Mimedefang] Easy way to tell message is sent from local machine?

[Justin King]

I do the following.

global:
$LocalRelayAddrs{"1.2.3.4"} = 1;
$LocalRelayAddrs{"1.2.3.5"} = 1;
$LocalRelayAddrs{"1.2.4.3"}  = 1;


filter_begin:
if ((-s "./INPUTMSG") <= (100 * 1024) and $Features{"SpamAssassin"} and
!(exists $LocalRelayAddrs{$RelayAddr})) {
...handle spam check...
}

-Justin
