Do you just queue messages from source addresses, so that you
don't generate more than one echo in a minute, or do you throw away
every message from that source address which was generated less than
one minute ago?
Also, how do you handle echoes of echoes? For example, if I
forged e-mail as being from echo@psi.net and addressed that to
echo@rohrbach.de (or whatever), would this generate an endless loop?
What if I put "echo@psi.net,echo@psi.net" as the return address?
Would you send back two copies?
Just curious. Thanks!
