Sorry for the delay in this answer.

like use milter-limit with different config for each instance (instance A 5 msg/sec,
instanced B 10 msg/sec).

It is possible to run multiple instances of a milter with different configurations. You
would have to change a group of options in order to separate the two instances:

	file			(on command line)
	interface-name		(interface-ip should be enough
				in which case leave empty)
	+smdb-key-has-nul	(should always be on for Postfix/postmap,
				 off for sendmail/makemap)

NOTE that the complete options file can be generated by:

	milter-link -help >milter-link.cf.new

If you want each postfix instance to use a different milter instance then postfix A should
refer to milter-socket of milter A, likewise for postfix B refer to milter-socket B of
milter B.

While not part of your request, you could also have one postfix instance refer to both
milter instances A and B, but at different points of order in the list of milters supplied
to postfix.

Remember that this all applies to sendmail equally.

You'll need to modify you start up scripts to start each milter with a different file=
option specified on the command line to override default the .cf path:

	milter-limit file=/etc/mail/milter-limit-1.cf
	milter-limit file=/etc/mail/milter-limit-2.cf
