how to limit the MAIL FROM domains for outgoing mail

Hi,

we have a rather complex postfix installation here and would now like to
restrict the domains being used for _sending_ mails.

I have really tried to find something in the vast documentation, but I
did not come very far (or did not understand the various pieced needed
for it).

We have some local clients here but also a couple of external customers
that we relay email for and some days ago I noticed that some of them
are sending mails with "illegal" sender addresses.

Our configuration is LDAP based, as we are doing virtual hosting, if
that matters.

So any thoughts on how to implement this?

Thank you

Udo Rader
