This ("ghost" message gets dragged in) happens to me all the time, 
Benny.  Drives me crazy.  (And it's still in r5462.)

But the cure is worse than the disease!  I did a Search recently and 
didn't know which Mailbox the results were in.  So I turned on Source 
Mailbox in the Search results.  Big mistake.  Now all of my Mailbox 
folders are infected with Source Mailbox disease!  That column shows up 
in every Mailbox folder now.  I didn't ask for this.

It takes up valuable space (and is completely unnecessary when you are 
in a Mailbox) and I can't get it to go away now.  I control-click in the 
"Date Received" column, un-check "Source Mailbox" and it temporarily 
goes away (but only temporarily).  I even control-clicked and selected 
"Use as Default Columns" (after "Source Mailbox" is gone/unchecked) and 
yet ... it still keeps coming back!

Is there some config file or XML file someplace where I can find this 
Source Mailbox enabled-by-default setting and disable it??  I looked in 
~/Library/Preferences/com.freron.MailMate.plist but didn't see anything 
relevant.
