Herewithin legalmail

It seems like you're referring to a legal document or a formal communication related to a legal matter. "Herewithin" is an archaic or formal way of saying "herein" or "in this document", which is often used in legal documents to refer to the contents of the document itself.

"Legalmail" is not a commonly used term, but I'm assuming you might be referring to a legal email or a formal electronic communication related to a legal matter.

If you could provide more context or clarify what you're trying to achieve, I'd be happy to help you with your legal document or communication.
