<p class="MsoNormal">I have been trying to create a very basic filter that looks up a string in the incoming log. However, it would not match any filter and would go to the default filter. I have tried both match() and message(), neither worked for me. Please
let me know if you think I am missing something.<o:p></o:p></p>
