I use Postfix with Postfwd as policy service. and I want to limit all 
outgoing messages with exceptions for several SASL users with HOLD 
verdict. I'm new to postfwd so I need configuration example for 
rate-limiting with HOLD verdict  (for instance limit all users 
outgoing messages to 10 messages per minute and HOLD messages 
exceeding that limit) also I need the same configuration to apply only 
to certain SASL users again with HOLD verdict (for example limit a 
certain user's outgoing messages to 100 message per minute and HOLD 
messages exceeding that limit). I appreciate if you reply with full 
configuration examples for these two cases.

Thanks.

Please note, that you should ask on postfwd's mailing list for these 
terms. Here is a sample ruleset, that limits User Bob to 50 recipients 
per minute:

POSTFIX MAIN.CF
==============
smtpd_recipient_restrictions =
        ...
        # place this BEFORE permit_* stuff
        check_policy_service inet:127.0.0.1:11040


POSTFWD CONFIGURATION
=======================
id=R001
    sasl_username==bob
    action=rate(sasl_username/50/60/HOLD)

The HOLD action is (from postfwd's point of view) not different to any 
other postfix action. See http://www.postfwd.org/ratelimits.html for 
more examples.
