A designated email address configured to receive all email messages sent to invalid or non-existent addresses within a specific domain. This ensures that no email is truly “lost” due to typos or changes in employee email addresses. For example, if someone mistypes “johndoe@example.com” as “jonhdoe@example.com,” the message, instead of bouncing, would be routed to this pre-defined receptacle.
The utility offers several advantages. It provides a safety net, capturing potentially important communications that would otherwise be undeliverable. Historically, this function served as a basic method for identifying and correcting address errors. Furthermore, the captured information can assist in maintaining an updated contact list by revealing outdated or incorrect email entries. Analyzing collected messages may also reveal attempted phishing or spam attacks targeting invalid addresses within the domain.
