[syslog-ng]Extra info padded when syslog-ng forwards syslog messages

Hi There, Is there a way for syslog-ng to forward syslog messages to another machine, without padding the additional information? (e.g. Feb 23 02:55:23 [203.208.161.105.28.128] 33: Feb 23 02:52:53.167 Singapo: %SYS-5-CONFIG_I: Configured from console by console) The [203.208.161.105.28.128] is the additional info padded. I have tried setting the option chain_hostnames=no, but to no effect. I would really appreciate it if you can shed some light on this matter. Thank you very much, Luke
