If it's a private email I wouldn't paste it (even with names removed), however you can relay the gist of the email. Information about who's buying & selling isn't market sensitive & is public information available to anyone with the appropriate subscription or a friendly broker, so no problems relaying that information. They wont give you market sensitive information anyway.
I've pasted emails before - such as the Supra milestone clarification, however they were aware I'd post it, they wanted it clarified anyway.
