smtpd_client_message_rate_limit customized for some user

[nik600]

Dear all

i'm using the smtpd_client_message_rate_limit setting to limit the
usage of my smtp service.

I'd like to know if is possible to have 2 different values of this
setting, and assign them only to some users.

i've also seen that i can force the check with
http://www.postfix.org/postconf.5.html#smtpd_client_event_limit_exceptions

but i need to change this value for a single smtp authenticated user,
not and entire network.

Is possible to do that?

Thanks

As documented, smtpd_client*limit are not a traffic control tool.
Their purpose is to block run-away and confused software.

The recommended way to rate-limit clients in different ways is to
use a policy service (such as postfwd or policyd).

Another option is to use port 25 ONLY for MTA-to-MTA traffic, and
to use the submission port for authenticated clients. Then, you can
apply different Postfix settings for different ports.

how to set port 25 ONLY for MTA-to-MTA traffic?
