Is it possible to allowlist sender addresses for email route to worker?

I need to be able to allowlist sender email addresses to be sure that the emails that they send will reach my worker via email route.

Is this possible by adding them as verified email address?

We have build a business application to store email attachments to R2. There is always one and the same sender address. Sometimes the emails are rejected (I can see this in the dashboard), but then the message is not delivered to our worker script, causing missing orders.
