If an "assistant" never replies to an e-mail, what is it "assisting" with exactly?
If this was a bank with a bank teller, you told the teller to never speak to a single customer, and then celebrated the fact that no one was able to social engineer them.
In security the interesting and challenging part is to differentiate between legitimate and illegitimate behavior. And that's different than just refusing all behavior outright.
Gonna give you a zero out of one hundred on "interesting"
If I hired an assistant and they replied to every single spam email, i'd fire them. Wouldn't you?
They're equally useless in the opposite direction.
No. Why? Id love to have an assistant that replied to spam, unsubscribing.
Spam that respects unsubscribes is barely spam these days.
Even if so, marking emails that make it the inbox seems useful to me anyway
