I do use Rmail, but not movemail from Mailutils, and not for imap and
other modern protocols.

So the only issue that bothers me here is: would the new code still
work with the old movemail, and how does the code detect whether it
invokes old or new one?

If this change is 100% backwards compatible, I see no reasons not to
install it.
