Off the top of my head:
----8<----
#!/bin/sh -e
sed -e '/^Subject: /!d; s/^Subject: //' /var/spool/mail/sms > "${smsfile}"
:>/var/spool/mail/sms
xargs -L1 /usr/bin/gammu --sendsms TEXT < "${smsfile}"
mv -f "${smsfile}" "${smsfile}.bak"
----8<----
No loops necessary.
By the way, what's gammu, and why is it in /usr/bin ?
