Hello mark!

This is indeed a routing problem and should be fixed instead of trying to stop
binkd from doing its work.

Routing should handle every case and never pack anything to your own AKA. This
is easily achieved with RNtrack, for example. My system will always resolve
final destination properly before packing anything (or discard mail that can't
be routed and send notification to sender).

I do not agree. Mailer reads outbound and delivers what can be delivered.

ml> call itself...

It would do exactly the same. Single line node would receive BUSY all the time
though.
