Why do we get answer review notifications sent from an email address for an interface that the staff member doesn't even log in to?

Environment:

Answer review notifications

Resolution:

When an answer is set to the review status based on a review on date or when the solved count is reduced to zero, the agedatabase utility sends an answer review notification. 

While answers can be published to a specific interface or interfaces based on the products, categories, access levels, and language, the answer itself is not associated directly to a specific interface. However, since answers can be written in a different language than the primary interface, notifications are sent from an interface that uses the same language pack as the answer. The interface is chosen ascending by interface_id with a matching language and an active default mailbox.

Therefore, answer review notifications can be sent from a mailbox that is on a different interface from where the answer is published. This email address is used even if staff does not typically log in to that interface or publish answers from that interface.
