[syslog-ng] Convert syslog to traps

Have a requirement to convert all incoming syslogs to SNMP traps and send it to another host. One option I could think of is to use program () destination.   When I tried this option, I find that syslog-ng is continuously sending newline characters to the specified program. i.e. even when no syslog is received, syslog-ng seems to be pumping newline chars to the specified program.   Also I read the warning message in admin guide that, it will open up the door to DOS attack.   Could someone let me know the best way to achieve this, please ?   Thanks in advance for the help.
