I use MsgTrack to handle this, although I've never had a malicious attack
(just misconfigurations).  MsgTrack has a number of techniques for doing
this, but the one I use is to bounce each message back to the offending
node.  In your example, 124/1113 would get a zillion messages saying
something like "You attempted to route echomail through here, and it
didn't work."

I don't think the author of MsgTrack is still in Fidonet; I registered a
few months ago, and got my key before he dropped out.  He may still accept
registrations, but if he doesn't the program will still do what you want.
