Hi, I have a E2010 SP1 UP3 server which is CAS/HT. When i telnet to the same same server IP and issue mail from, it issues a following a error 530 5.7.1 client was not authenticated.

Hi On the default receive connector with the Server name, go to properties and make sure Anonymous option is checked, then only it will allow the other client to autenticate and external mails can come through... Thank you
