I recently informed my users that I was changing the relay function of our server such that a username/password would be required to send mail (SMTP Auth). I made the change Sunday night. My clients made the change to their mail throughout the last month. Testing went smoothly and I had no problems monday. Today I got multiple calls from my users complaining they could not send mail outside their domain. They'd receive bounce back messages that say:
"Requested action not taken: mailbox unavailable. [SMTP Error Code 550]" It was my understanding that if I set IMail from "relay mail from local users only" to "No Mail Relay" and the user had SMTP Auth enabled in their e-mail client, they would still be able to send mail. I am parsing through my IMail log trying to discern what might have changed between yesterday and today, but am coming up short. Any fellow IMail admins that use SMTP auth and 'no mail relay' have any idea how to fix this? I would very much like to have SMTP Auth working with no mail relay. Thanks!
