What i would like is :
For example, my postfix relay accepts about 1000 emails (1 shot)
from a SMTP client, then the postfix server relays them with the
rate of 5 emails per domain per second without REJECT.
As documented, the minimum delay is 1 second.
Do you know if postfwd permits to have this behaviour ?
Not possible; postfwd limits input, not output.
Depends on your setup; we run postfwd on our relay servers, with a
very simple ruleset;
==
id=LIMITSEND
action=rate(sender/150/3600/DEFER '$$sender' exceeding rate limits)
==
In other words, if a sender sends more than 150 messages in one hour,
defer the next attempt. This allows people to mail merge in Outlook
via their local Exchange server and whatnot, it will just take a
number of hours that is roughly equal to the number of messages
divided by 150.
As said, this requires that you have a setup where the submission
servers relay via the server that runs postfwd, and the retry interval
etc. comes into play here. But one could use the multi-instance
postfix option for example to set up a submission instance
specifically for this type of client, which accepts everything and
then relays it through the actual sending server to the outside, with
custom retry intervals and such.
Another option may be to put the whole batch on hold, and then run
some custom scripting that requeues messages based on limits you
specify.
It all depends on what you are trying to achieve, though. Is one per
second really a problem in terms of delays? A thousand e-mails take
less than 20 minutes to deliver to a single destination that way.
HTH,

you can try POLICYD, i limit with this outgoing and incoming mails.
