+ which is then sorted with a python script using Bogofilter for spam detection.
+ This is generally a great deal faster than a shell-scripted approach.
+ This approach introduces a workflow built around a "watch" tag. Here, the user
+ is only presented with threads as they are started. At this point the user can

+ "inbox", or ignore it. This provides an excellent means for dealing with a
