I just had a look at the code, and it is indeed possible, though I did
not remember implementing it: you can ratelimit sessions, recipients or
bytes.

The rules would by like this (not tested, this is a wild guess):

list "USERS" addr { 158.227.4.29/16 }
ratelimit "MESSAGES_PER_HOUR" rcpt 200 / 1h key "%f%i"
ratelimit "BYTES_PER_HOUR" data 500M / 1h key "%f%i"

racl blacklist list "USERS" ratelimit "MESSAGES_PER_HOUR" \
    msg "LIMIT_1H. You have passed the recipient limit".
dacl blacklist list "USERS" ratelimit "BYTES_PER_HOUR" \
    msg "LIMIT_1H. You have passed the bytes limit".

Of course it works even beter if you use authenticated SMTP and have the
User identity in the key.
