Most likely because ~/Library/Application Support/MailMate/Messages is 
(usually?) a symbolic link which points to the absolute full pathname of 
your actual message store and that path does not exist on the new 
system. If you had a "Custom Location" set for the Messages folder (in 
Preferences->General) you may be able to fix the problem by switching it 
off, restarting MM, and switching it back on. If you didn't have that 
set, you can recreate the default symlink with:

ln -sfn ~/Library/Application\ Support/MailMate/Messages.noindex 
~/Library/Application\ Support/MailMate/Messages

If you had a "Custom Location" set for the Messages folder on the old 
system, that copy missed all of your messages.
