Hello:
Another approach, for sendmail as MTA, is to use rate-limit feature of
milter-greylist (http://hcpnet.free.fr/milter-greylist/).
Can put different rate-limits for users based on (IP,sender) tuple.
We're using it, with different limits for Webmail IP (RCU), clients in
my network and clients anywhere else.
As it can use milters this could serve for postfix too.
Best Regards.

...as you said: per IP.
stop using ip alone auth
If the IP is that of your webmailer... one user causes the whole side
to be throtteled... (not that funny unless every user has its own
roundcube)
best option is the old policyd with sasl auth rate limit, it does not
care of ips at all
You need some more magic software (plugged to postfix or to
roundcube) for this. Postfix can't help you out (for Squirrelmail
there are such addons).
squirrelmail is nice too, but its not a good rate limiter for users
with cellphones
http://www.policyd.org/ use v1, only use v2 if you have amavisd aswell
