Question
What does No transport set by system filter in a log line mean?
Answer
Your system filter contains a pipe or save or mail command, but you have not set the corresponding option which specifies which transport is to be used. You need to set whichever of system_filter_pipe_transport, system_filter_file_transport or system_filter_reply_transport is relevant.
