Secure Alias setting
Question asked by Brian Davidson - 2/20/2015 at 4:46 AM
Try as I may, I can not find this setting referenced in release notes - can anyone help me locate it?  Has it made a difference to anyone?

Prevent Incoming Spam with Secure Aliases

Email aliases are great for saving time when sending messages to multiple users that you communicate with often. However, if a spammer gets ahold of your company aliases, it could mean an increase in spam. SmarterMail 13.x adds alias protection by including an option to only allow emails to be sent from addresses that match the alias domain.

Hi Brian,
This setting can be found when configuring the alias. Log in as the Domain Admin and go to Settings > Domain Settings > Aliases > New. The last setting you'll see in the modal window is "Internal only". This is what you'll want to check in order to reject emails from addresses not matching the alias' domain name. 
Please let me know if this helps you out so we can mark the status of this thread accordingly. 
Thank you!

Thanks Andrea. For whatever reason, I read this to mean there was a more global setting. Must have misread the information.

I can see why you would think it's a global setting. I'm glad I could help clarify. I'm going to go ahead and mark this thread as answered. Thanks for following up.
