Hello,

First, I love postfix.

I have SASL auth via dovecot working well (pulling from a pgsql db) and I am
clamping down on possibilities for spam by further rate limiting senders
emails to a daily quota. postfix-policyd-sf is not suitable due to mysql only
and I really don't have the time to hack it.

I CAN do native pgsql maps tho, and have a token bucket schema/views/plpgsql
rules ready to use.

What I'd like to accomplish is this (in english):

1. Authenticate user
2. Reject if not authenticated
3. Check users remaining send quota
4. If number <= 0, reject
5. Else allow

Now the smtpd_*_restrictions work on a first hit basis. So would this mean I
need to set up a second instance on the localhost, bypass all the checks and
do my sending rate limit there? Or is there a simpler way with the restriction
rules?

TIA for you help!
