Unless I'm missing something in your description...  Yes, that's normal
behavior for an MTA.  Anyone has to be able to send mail to your
users, otherwise they can't receive email from the Internet.


This is the way it should work:

Anyone (authorized or otherwise) should be able to send mail to users
of your domain.

Authorized users, or users from an allowed IP block (RELAYCLIENT in
smtpaccess) should be able to send mail anywhere.
