I have been reading the documentation for smtpd_sender_login_maps and

From the docs:
"In all cases the result of table lookup must be either "not found"
or a list of SASL login names separated by comma and/or whitespace"
Thats not manageble in some scenarios.
Since that list could be a LDAP lookup I'm going to research that
option.
note that postfix compares envelope senders to those in database, so you
must make sure that the envelope sender matches address in From:
I'm using one alias file. I'm going to parse that to get the possible
From: fields and work from there, after that I can get the rest of the
cases with a getent passwd.
That way I can build a hash table and don't need to mess with LDAP.
It would be nice to have a option to specify a list of allowed domains.

I need to limit the domains in "mail from" for autenticated users

the documentation and did not reached any conclusion.
My best guess is that is some configuration that may be passed as
an option to submission and smtps.
What is the proper way to do something like that?
