Can't mass SMS contacts without an email address.

We have recorded that if a contact has no email address that messages to them will not be sent.

It will exit on (4.5.4) line 1250 of CRM/Mailing/BAO/Mailing.php

Changing the error to CRM_Core_Error::debug_log_message(ts('CiviMail will not send an empty mail body, Skipping: %1 mailParams: %2 ',
array(1 => $email, 2 => print_r($mailParams, TRUE))
));

Outputs:

CiviMail will not send an empty mail body, Skipping: mailParams: Array ( [Reply-To] => "FutureFirstSMS" [Return-Path] => bounce+b.4727.502649.d6b81fd073885692@futurefirst.org.uk [From] => "FutureFirstSMS" [Subject] => [List-Unsubscribe] => )
