I need to have a unical user who can send emails without
authentication and only on my domain how can I achieve that ?
How can you tell wether it is this user or not if it is not authenticated ?
I can tell it is a user because it is in my alias_maps
take a deep breath!
you can tell NOTHING without authentication
your alias maps will not replace authentication
so what you try to do is broken by design
I have no problem to breath ... I was just asking I'm not postfix expert
it is indeed very problematic to let a client send a message only because it
claims to be a certain sender. Any client can do that and given the fact that
there are dictionary attacks taking place all the time you shouldn't do that.
As I understand it the client you want to connect to your server is not
capable to do SMTP AUTH. Will you be able to identify the client by its static
IP? Will it connect comming from a known IP space e.g. a VPN IP range? Or is
it able to use a TLS client certificate?
If we find a criteria we can solely attribute to your client will have
something the server can trust in.

Oh sorry yesterday I missed your questions.
The client would be on my local network only /192.168.0.*/ and for any
email sending I configure postfix so that it tries to use TLS if the
client support it.
So to sum up I want the user /maintenance/ to be able to send any email
only from /192.168.0.*/ and only to my domain /sample.com /(to avoid
spaming if an indelicate user understands this user doesn't need
authenticating).
