Debug Channels

The various SpamAssassin scripts have a debug option (-D) which can optionally take a list of channels which will restrict what information is displayed. People have asked which channels are available. However, the channels are dynamic based on the code that is running. When looking at the debug output, the first word (pre-colon) is the logging level (dbg, info, warn, error,) and the second word (pre-colon) is the channel. ie:

[20784] dbg: message: main message type: text/plain
[20784] dbg: bayes: DB journal sync: last sync: 1148309062
[20784] dbg: check: is spam? score=-0.156 required=5
[20784] dbg: check: tests=BAYES_00,MISSING_SUBJECT,NO_RECEIVED,NO_RELAYS,TO_CC_NONE

has the channels message, bayes, and check. While the channels are dynamic in nature, below is the standard ones that are in use (this is not a complete list).
