I am thinking setting up two mail servers. One for income mail only and one for outgoing mail only.
With this type of setup, can I turn off the all the relay function (including authorized users) on the income mail server and still recieved mail from in and out of the domain? (Since no one will be sending email through this server)
Also, can I turn off "Anonymous Access" in Authentication of Access of SMTP server of the outgoing mail server? (Since no one but authenticated user will be sending through this server and it doesn't need to accept other smtp server's request.)
Is this an ideal setup or there are better way to do it.
