📝 Preliminary Checks

• I tried searching for an existing issue and followed the debugging docs advice, but still need assistance.

👀 What Happened?

Using a catch-all alias like "@example.com -> mail@example.com" will not allow users to send emails on behalf of arbitrary addresses within the "@example.com" domain or to spoof them.

When I add a specific alias like "test@example.com -> mail@example.com", I can send emails from "test@example.com". However, this does not work with the catch-all alias.

Is this behavior correct? If so, what changes do I need to make to achieve the desired behavior?
