Yes, I am, though by default both are postfix on my system.

I've already fixed the problem for myself, as follows:-
Mutt accepts an mbox with no blank lines (not surprising as it's
what it creates itself).
I have created a derived class of my own from the Python library
class mailbox.mbox and I have overriden the _pre_message_hook(self,
f) method so that it doesn't append a blank line before appending a
new message to an mbox. I use this derived class in my filter
program which delivers mail to my incoming mbox files.
So I have fixed my particular problem.
It does seem to me though that mutt doesn't necessarily do the right
thing to detect whether an mbox has been 'modified' or just appended to.
