If "outgoing" includes smtp relay service (and thus "incoming from PCs"),
you might want to guard against compromised PCs being used by spammers.
Thanks to laptops being carried in and out, do not rely on network
firewalls.  Requiring smtp auth helps though; the spam and virus engines
don't seem to do that yet.  (We're waiting for one that puts its junk in
an Outlook Express outgoing queue to be sent with smtp auth later.)

You can put any conditions you want around the call to Spamassassin.
We skip it:

if (defined($SendmailMacros{"auth_type"}))

if ($RelayAddr eq "127.0.0.1")

and also if $RelayAddr is certain other local IPs that we trust.
