if a server is sending bounces instead reject messages it is wrong configured > Backscatter is done with bounces. Not all bounces are backscatter. the one and only reason why a bounce is acceptable is to *your* users beause the remote MTA rejected a message and after accept a incoming message the LDA does not accept it because quotas whichthe MTA can not check for * if you accept a message and the RCPT is unknown -> config error * if you accept a message and use a post-queue spamfilter you must not bounce avoid such filters there is no other valid reason accept a incoming message and after that send a bounce - that's the Microsoft Exchange way accepting and then send bounces "user unknown", but this is unacceptable behavior
