You misunderstood my original email. Users have two folders: one for 
reporting spam that wasn't identified as spam (the "Spam.Report" 
folder), one for rescuing ham that was misidentified as spam (the 
"Spam.NotSpam" folder).

Thus, there is no "implicit" behavior - putting a message in one of 
those folders explicitly tells the system "learn this message" or 
"unlearn this message".

How is that not visible to the end-user?

Heh. I see. But the user expects messages in the Ham folder to 
disappear and be automatically redelivered to their inbox.

Because my system uses SpamAssassin's "report_safe" feature (see 
http://spamassassin.apache.org/full/3.1.x/doc/Mail_SpamAssassin_Conf.html#item_report_safe). 
When a message is identified as spam, instead of modifying the 
original message, the user receives a report message with the original 
message attached as a text/plain attachment. This makes reading the 
original rather difficult (on purpose). Thus, one of the benefits of 
moving the message to the NotSpam folder is that the message is 
restored to its original form and redelivered.
