I just set up Postgrey yesterday and it works just fine.
One thing that got me thinking though was that if I have greylisting
check Before reject_rbl_client, shouldn't the rbl check be skipped if
the IP get's greylisted and Then checked with rbl when/if it passes the
greylisting? Or am I thinking wrong here?
