Personally, I don't mind it at all. If a remote email address isn't set up correctly to receive emails with proper SPF records, it is their problem to deal with, not mine. My responsibility regarding email only extends to the point where the remote server accepts the email. Once that is done, it is their problem if they can't relay it properly.
