consolidate everything into postfwd.
Additionally, rate limiting is typically done on outgoing mail,
while RBL checks are typically for inbound mail. This might be a
good time to investigate multiple postfix instances to separate your
Anyway, to answer your question about which to use first; it
probably doesn't matter. Rule-of-thumb is to put less expensive
checks first -- that suggests rate limits with local table lookups
first, then the more time-consuming RBL lookups next. But in this
situation it probably doesn't make much difference since they are
checking different mail flows.
