SMTP error codes?

Hi!

I'm playing around a bit with my new mail server at the moment and I
wanted to use a whitelist with allowed senders. Now I'm looking for the
correct error code to tell a sender he's not allowed to send me an
email. Should I use 550, 554 or something else? Any ideas?

Thanks in advance

Mario

I'd prefer 550.

From RFC 2821 (http://www.ietf.org/rfc/rfc2821.txt):

550 Requested action not taken: mailbox unavailable
(e.g., mailbox not found, no access, or command rejected
for policy reasons)
