Hi,

running in problems with KMail I decided to switch to dovecot-imap & thunderbird on my kubuntu 12.04 64 bit (so I can read my imap-folder-mails with KMail again if it gets more stable)

What I did:

• I wrote a python script to convert my KMail mails folder to a thunderbird mailfolder (directory tree containing mbox files and *.sbd folders)

• I created a fake pop mail account in thunderbird and imported the whole mail-structure (i just copied it)

• I create a local imap account ( so I have a ~/Maildir dovecot folder in my user dir)

• In /etc/dovecot:

  1. /etc/dovecot/10-mail.conf (line 10) I set: mail_location = maildir:~/Maildir:LAYOUT=fs

  2. /etc/dovecot/20-imap.conf (line 57) I set: imap_client_workarounds = tb-extra-mailbox-sep

Now I want to copy the whole mailstructure from my imported fake pop mailfolder to the dovecot imap folder.

What happens:

Lets say my source structure is

mailfolder1

• mail1
• mail2
• subMailFolder2
  • mail1-in-subMailFolder2
  • mail2-in-subMailFolder2
  • subSubMailFolder3
    • mail1-in-subMailFolder3
    • mail2-in-subMailFolder3

I thunderbird (version 15) I drag and drop my mailFolder1 to the imap folder and I get:

mailfolder1

• mail1
• mail2
• subMailFolder2
  • subSubMailFolder3

as you See only the mails of the *TOP* folder are copied. All subfolders are created but they contain NO MAILS.

Did somebody experience the same problem???

Otherwise I will write a python script to do that (I dont hope to need to write a mailclient in python ;-) )

Any hint is greatly welcome.

Anton
