IMO you are confused. That RCPT rejection was logged,
doesn't mean that it was send, and even if, i am sure that
attacker will not receive it.
IMO if exim will not process all received commands and log
rejections, important info can be lost (eg. ratelimits, stats,
etc). Anyway, if you care about output flushing on delays,
there is control option to manage that. IIRC the PIPELINE is
exactly mentioned in its description...
BTW, the RBLs are good not only for rejection, but eg. to
disable PIPELINING for suspicious hosts too...
