Due to the origin/content of the different types of messages, I'm using different encoders for each of the three types (in each of the three appenders). The only way I see being able to do this is with multiple appenders. Can you think of another way to do this with logback?

Are the encoders custom? Anyway, you could have an encoder which encodes 
in different ways depending on the event.

No, 1.2 and 1.3 simply do not allow multiple appenders writing to the 
same file.  --
