invalid literal for int() with base 10 (Mailbox does not exist)

[EB]

I’ve added a mailbox to import through the gui and ran import.sh.
After some time I receive the following error:

root@piler:/usr/libexec/piler# /usr/libexec/piler/import.sh
/var/piler/imap /etc/data
/var/piler/imap /var/piler/imap
Traceback (most recent call last):
  File "/usr/libexec/piler/imapfetch.py", line 193, in <module>
    main()
  File "/usr/libexec/piler/imapfetch.py", line 177, in main
    process_folder(conn, folder)
  File "/usr/libexec/piler/imapfetch.py", line 65, in process_folder
    n = int(data[0])
ValueError: invalid literal for int() with base 10: b"Mailbox doesn't exist: INBOX/_Test (0.001 + 0.000 secs)."

A mailbox without any folders does not throw this error. Seeing no one else ran into this made me think it has something to do with the underscore. So I excluded this folder and then ran into the same issue with a folder with an exclamation mark (INBOX/!Temp).
How can I make this work without having to rename each and every folder?

Apparently this is caused by special characters in the foldernames (i.e. !, & and _).
How can this script be modified (if at all) to work with these chars in the foldernames?

Can you create a test imap account for me with such folder names? If so, send me the login details to my email (Run piler -V to see it). A few spam emails would be fine in the mailbox.

I don’t know any python, but added the below lines and that made it work (or at least it fetches the folders and contents).

   if '!' in folder:
       n = data[0]
       n = int(n)
    elif '_' in folder:
       n = data[0]
       n = int(n)
    elif '&' in folder:
       n = data[0]
       n = int(n)
    else:
       n = int(data[0])

I put that instead of the line “n = int(data[0])”
Now it seems to crash on other things… Not sure if it is specific mails/folders or the amount of mails/folders….
Looking into this at the moment….

Also, I’d like you to try the import with script on the master branch: https://bitbucket.org/jsuto/piler/src/master/util/imapfetch.py

Finished without any errors

Then case is closed :-)
