MSU Listserv

I would like to have the option of enabling Spam processing on my MSU mail 
without having ***SPAM*** put in subject lines. 

Does anyone know of a way to enable the Malmail Setting "Move to SPAM 
folder" and have the Spam automatically put in the Inbox instead?  I tried a 
filter for "X-SPAM-LEVEL starts with *****", but it does not move messages 
to the Inbox. 

Or does anyone know of a way to retrieve mail from the SPAM folder using 
POP3 (we have an Imail server which allows us to use a special 
username-mailbox syntax to retrieve mail from a folder other than Inbox). 

Or do you have a better suggestion? 

Thanks,
