It actually will not hit on anything at all, if you are rejecting based
on ZEN -- UNLESS for that very tiny timing window between accepting at
SMTP stage and later SA filtering.
Mind you that requires the previous DNS lookup to time-out before SA, so
either there's quite some delay, or another mail from that IP has been
received shortly before, so it might time-out between SMTP and SA. Well,
or you're using two independent DNS servers... ;)
