Trying to better lock down Default Virtual Server SMTP Authentication settings
Posted on 2006-06-20
I am trying to understand how to better lock down exchange server 2003. I don’t have any POP3 or IMAP users so I don’t have the need for any users to relay mail. All of my exchange users are using Outlook in exchange mode only. Keeping this in mind can I safely disable "Basic authentication" and "Integrated Windows Authentication" under the Default Virtual Server SMTP Authentication settings?
Also from my understanding I will need to keep “Anonymous access” enabled or otherwise other email servers will not be able to send mail to this server? Is this correct?
