Is there a solution to force postfix to check the MX of a domain name

why ?, an a record is fine with me?
I can not prevent users from adding the domain name in the mail
system.
We limit the rights, but the solution is not optimal.
when some fools add domains, ask postmas...@example.org or there so new
domain if thay need you to be mx for there domain, do this before
activate mx hosting, did thay even paid you ?
For example, if a user adds the domain "mma.fr" in the mail system,
it
will receive all emails from users who are sending to MMA.FR.
The problem is that MMA.FR does not point to the mail server and all
messages are "stolen" by the user with a catchall...
this is not a postfix problem, but a user auth problem your site makes,
its fine to add domains, but plese verify with a email to
hostmas...@example.com before its gone in air, most often you will see
problem is gone in postfix that way
If I knew in advance the fields, I would use the file "transport" ...
But it is impossible :(
this is a fix for something that is out of your control
I would always force Postfix to send its messages to the outside and
never try to deliver locally emails.
So I'm sure the mail arrives at the inputs of the MX domain name and
no message can be "stolen" locally.
exactly ask domain owner first
