ID: 1157 Title: Fixed SMS plugin on at least debian (distrs which have no sendsms/smssend) Component: Notifications Level: 1 Class: Bug Fix Version: 1.2.5i6 Some distros do not provide the sendsms/smssend script with the smstools package. In this cases the script for sending SMS did not work. This commit adds a dedection when smssend/sendsms are not available whether the spool directory at /var/spool/sms/outgoing is available or not. When it is available, the SMS notification plugin drops a file to this directory which should then be processed by smsd.
