Is there an automatic way migrate a thunderbird mailbox to sylpheed while preserving the folder structure. I tried the importexport extension for thunderbird and got a directory with multiple mbox files and subfolder which contain again mbox file.
For example
inbox1
inbox2
foo.sdb
foo1inbox1
foo2inbox1
foofoo.sdb
foofoo1inbox1
foofoo1inbox2
foo2.sdb
foo2inbox1
foo2inbox2
Sure I can import manually every single mbox file with sylpheed, but is there an automatic way to import all at once and preserve the folder structure?
