Well, this is something new in Opus 4.7, or at least I see it for a first time now. No such security gates seen before.

I am asking it to process am email, provided as eml file, but the email contains my address, and my sisters'. And this is treated as personal sensitive data, that it does not want to process. If I just copy and provide the mail content, without the real email addresses, it works fine :D

Have you seen something like this, or anything similar?
