 - scoreboard: one mail from one source addres in one minute time window

      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?

please, see the other answer in this thread.


      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?

X-Loop:


      What if I put "echo () psi net,echo () psi net" as the return address? 
Would you send back two copies?

No.

      Just curious.  Thanks!
