you only have to publish SPF info for the machine that you use to
relay mail, not for the ip you are using to send email. Usually people
send email (using Outlook,Eudora,etc..) to a relay server (i.e running
Exim), in that case as you have authenticated to the server it will
not use SPF to test your ip. The only case that it will be a 'problem'
for mobile users is when that user try to directly send the mail to
the destination servers, which is a very bad idea as it will be
originated
at a dialup ip's and thus will be rejected by some servers. If you
really insist on doing that, then you could a) do not publish spf info
for your domain or b) publish spf info allowing any ip to use your
domain.
BTW there are LOTS of reasons to avoid directly sending mail to
destination servers and use a good server for relaying.
