429772 - Thunderbird does not import or export mbox files

Status: RESOLVED DUPLICATE of bug 63389

(Thunderbird :: General, defect)

Description

[Martin Pagnan]

User-Agent:       Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14

First, the advice stated under Thunderbird "FAX" does not work. It states to import an mbox file select it in the import window. However, the import function will not allow one to pick the mbox file, "the one without an extension". It requires that one pick a .js or some other such file. Then, importing from an old file it will correctly identify the accounts contained in the directory but it will not import the files. It simple reports "import complete. No files found". Still, if I browse the file with a simple editor, the file definitely contains the individual emails. 

Reproducible: Always

Steps to Reproduce:
1.Put an mbox file in any directory.
2.Try to select it for import with the import tool.
3.Sit and cry while Thunderbird refuses to see it. 
Actual Results:  
Thunderbird cannot be made in import. 

Expected Results:  
Mail from my old account is successfully imported. 

The process will not work even with Thunderbird mbox files with or without the .msf index file. It will not work if I created phoney profile.ini and put the file in a profiles directory beneath it. What I really need is a way to import mail from my old machine, the email is in Thunderbird, and import it into my new machine either over my net or directly. I do not want to import everything, just selected files.
