With Thunderbird 3.1 I can now "delete" a folder which moves it to Trash. But I cannot remove the folder in Trash.
The following is from the Thunderbird log file:
248[6814c00]: 8103800:imap.kzone.ch:A:SendData: 64 rename "test10" "Trash/test10"
248[6814c00]: 8103800:imap.kzone.ch:A:CreateNewLineFromSocket: 64 OK Rename completed.
248[6814c00]: 8103800:imap.kzone.ch:S-Trash/test10:SendData: 70 delete "Trash/test10/"
248[6814c00]: 8103800:imap.kzone.ch:S-Trash/test10:CreateNewLineFromSocket: 70 NO Invalid mailbox name: Trash/test10/
I can confirm that dovecot cannot delete a folder if the name is ended with a slash.
b list "Trash/x" *
- LIST (\HasNoChildren) "/" "Trash/xx"
- LIST (\HasNoChildren) "/" "Trash/x" b OK List completed. c delete "Trash/x" c OK Delete completed. d delete "Trash/xx/" d NO Invalid mailbox name: Trash/xx/
Let me know if that's a Thunderbird bug and I'll open a ticket with Thunderbird. (But I hope it's a dovecot bug as dovecot bugs actually get fixed, fast. :-)
