This drove me nuts, too. While not the tab key, I put this:

{
	"0" = ("makeFirstResponder:", "mainOutline"); // move focus to message 
list
	"9" = ("selectNextKeyView:"); // move focus to next pane
	"8" = ("selectPreviousKeyView:"); // move focus to previous pane
}

in ~/Library/Application 
Support/MailMate/Resources/KeyBindings/srb.plist, and added 'srb' to the 
'Custom Key Bindings' field in the General preferences, restarted 
Mailman, and then hitting the "0" key will take me back to the message 
list. Better than nothing for me. I still find myself fruitless hitting 
Shift-Tab sometimes.
