Thanks. I read the email.

This is the key sentence - right at the end.

"She told them she wants them to take the land and just free her children, but they refused to do so and they told her they are going to hold her in prison forever and her children too"

All the stuff mentioning Nicole Kidman, Mulder etc could be name identifiers eg a woman named Nicole is who the person refers to.

It sounds like an alert about a "problem" woman they need to take care of. A woman whose kids have been kidnapped and is demanding them back. Or a blackmailer...
