Hi!

Thanks. I did it and it worked exactly as expected. But, when I tried
exactly the same on an older Postfix, I found that the behaviour was
exactly the opposite to what's stated in the FAQ.

For Postfix 20010228pl02 it worked out of the box. I just had to add a
'check_relay_domains' at the end of the
smtpd_recipent_restrictions and list people who can't post to the
suggested file of 'restricted_senders'. For Postfix 19990627 I had
to add the 'e-mail' of people who are allowed to send, so I've changed
the file to 'unrestricted_senders'. It would be interesting that this
different behaviour is present at the FAQ.

Thank you again.
