Hello,
We have a spam issue in which emails, sent originally to another email address, are then being forwarded in bulk to one of our support emails.
Since forwarding an email changes some of the headers, standard email blacklisting options do not work. The emails are not inherently "spam" in a traditional sense. Many of the emails aren't even actually spam, they're newsletters or just garbage that is meant to just be annoying, so they have a low spam score that gets through filters.
As the "spam" is only being forwarded from one email, I would like to filter by the "Resent-From:" header, as it is always the same email address.
Is there a way to accomplish this with exim configuration?
