If your clients have dynamically assigned IPs which change periodically, then they should be sending all mail out via a fixed smarthost. Of course, that doesn't prevent people who switch on features they don't understand from rejecting your client's emails. To answer your question: yes, you can remove any header in Exim and replace it with anything you want. Amending the Received: headers is not at all advisable as there is a set format for them. If you want to "hide" the originating IP address, then removing all the Received: headers is the way to go, perhaps adding an "X" header (say X-MyDomain-Track:) with something in it that you understand, like the message-id or the hash you previously mentioned.
