The mobile users aren't using your server; they're using someone else's 
server to send out e-mail that should be going out of your server.

Your SPF record is showing the following:

"v=spf1 a mx -all"

Which means only your MX's are allowed to send mail out as 
thematthewsgroup.com; if your users are *actually* connecting to your 
server, and they're authenticating themselves properly (not using 
POP-before-SMTP but *actual* SMTP AUTH), then your SPF checks should 
work, in theory. All of mine do.

What are you using for SPF? In the meantime you can add "~all" instead 
of "-all" to mitigate (not eliminate) the problem while you find out 
what's wrong.
