I am trying to achieve the following. Download all messages from mail server(and remove downloaded messages from server). Downloaded messages should be in a local mailbox preserving folder structure as was defined on server. The download process should be automatic and shouldn't create duplicates.
I am on OSX and looking for solutions using Apple Mail or Thunderbird or similar.
So far I have found POP is not the way to go (as it looses folder structure and potentially can cause duplicates).
The solution described here seems very good but isn't yet available for thunderbird or apple mail. http://getsatisfaction.com/mozilla_messaging/topics/auto_archive_and_keep_folder_structure.
The other alternative is outlook which has auto archive which is paid and I think exports to pst instead of the more common mbox format.
Yet another alternative is http://www.pop4.org/ which adds support for folder management to POP. Which I don't think is going to become usable soon.
Any other better solutions.? Thank you
