(PowerShell) Get the Email Received Date/Time

Get's the date/time from the topmost Received header. The date/time of when you received an email may be different than the date/time stored in the Date header field, which if truthful, is the date when the email was sent.

The Received header field will look something like this:

Received: from mail.example.com (mail.example.com [99.255.255.99])
 by inbound-smtp.us-west-2.amazonaws.com with SMTP id 72ma443vs1g0o6vqd8erojkpss35s0dt32h323o1
