Hi All,

Mail can be submitted locally in several ways; smtp is usually not the
most prevalent way.
sendmail(1) submission is not subject to any of the smtpd_*_restrictions
tests, so this is hard to implement there.
You could set up a second postfix instance and relay all
sendmail-submitted email through that, but this does not make for a
particularly manageable system as there will be a lot of duplication of
effort.
(e.g. NDR)
Why do you want bounces to be handled separately ?
I suspect a scheme to not send bounces.
This is a Bad Idea; you should always send (valid) bounces.
If you wish to not send bounces for mail you accepted, don't accept the
mail to begin with.
Proper configuration of smtpd_*_restrictions is key.
You may also want to consider not allowing user sendmail(1) submission
at all (it is usally required for system-generated mail); instead, use
the standard submission mechanism for all locally-submitted mail.
or being delivered to it by some smtp client. Is there a easy way to
relay all mails generated through postfix to a different custom
transport rule while saving the general emails coming though other
smtp clients which will use the general rules on postfix.
If you require valid (i.e. postfix-controlled) sender addresses on
submission, then you can use sender_dependent_default_transport_maps for
this purpose.
If you don't, there really is no sane way to enforce this.
We use postfix 2.9 for our systems.
That has all of the above functionality.
