I'm seeing alot of arguments in the form of "I have mobile users and they aren't going to be able to send email if you use injection IP mail filtering approach X" (where X is SPF, MX+, or what have you); which take the same form as the arguments people made against closing open relays.
So, try to authorize the sending host rather than the path (mail from / sender etc) You neatly work around that problem
