I just transfered my domain from a third party which hosted Horde as my mail client to Google Apps.  I need to import all of my mail from the mbox files I exported from Horde into Gmail now.I tried GML but it chokes on the mbox file saying that it is not well formatted.  I have tried exporting multiple times from Horde and from multiple accounts.  I get the same error on all of the mbox files.Any ideas?
