A reject 'in SMTP-session' will not cause backscatter... you have not accepted the message at all, it is up to the server trying to deliver the message to decide whether it will backscatter to the From address that it probably forged in the first place. If it didn't forge it then it was an open-SMTP relay, and shouldn't be trying to deliver the message at all... it is the cause of any possible backscatter.However, spam was not rejected, although I think that this might cause unnecessary backscatter in the case of probably forged From addresses, which is a little unfair.
