[PATCH] Corrected return values in prep_for_email;

["Alan Raison" <alan@theraisons.me.uk>]

Function was returning 0 for failure and 1 for success which was breaking
the logic in the main loop.

Corrected to return 0 for success, 1 for failure.  Function now also returns
in all cases, rather than exiting.
