I'm having great difficulty in finding out how I'm supposed to do this. I have applications that need to send e-mails form our domain.
I've had a suggestion to use shared accounts, but I don't think you can log in as a shared e-mail account (ex: [email protected]), and let alone all of my applications would share a password (ack!).
Do I have to purchase mailboxes for every service and application account? Is there a way to run a non-human user account?
