What about defining the accounting rules at the beginning of the config
file and reuse them later?

# accounting "<rule name>" "<key>" (msgsize|msgcount) <limit> <duration>
accounting 'usracct" "%f" msgsize >= 300MB 24h
(...)
racl blacklist list "users" accounting "usracct" msg "too many messages"


Here we would maintain a size count of messages for each sender (%f). 
The use of a format string enable accounting against whatever you want 
(IP, sendr, receiver...).

Problem: do we just reset counters every <duration> (here, 24h)? Or do
we try a sliding count? That would be much heavier to implement.
