I've setup a working postfix server except that all incoming mail is rejected.
When I try to send mail via telnet:

If there is any other information I can provide please let me know.
EDIT: It seems like the server is requiring authentication to receive mail here. It doesn't seem to be host-restricted—using telnet from the server itself still causes the mail to be rejected. Authenticating with SASL and then sending the email works fine.
So, it seems that the problem is the server expects authentication for mail to be delivered at the final destination, which it shouldn't. Ideas?
