I was using alpine for sometime when I decided to add in thunderbird to the mix (for its GUI). I have set up thunderbird as a Unix-movemail account and the outgoing server as localhost. This made thunderbird to move the entire inbox file (an mbox file) from alpine's directory (/home/Mails) into its own (/home/.thunderbird/.../Mail/localhost) and also created new supporting files like sent, draft etc files (of mbox and .msf types) here.
This has created two problems:
* I can no longer access my inbox through Alpine - I see an inbox with zero mails here.
* The older sent-mails files (one file for each month) is still stuck at the original alpine's directory.

Now, how can I fully sync both and continue to use both of them?
