Renaming/Deleting Folders with Mozilla/Netscape

[Bernd Nies]

Hi,

We're running Cyrus IMAP 2.1.12 on Solaris 8. While testing with Mozilla 
1.3 and Netscape 4.x I stumbled across a possible bug with Cyrus.

After deleting or renaming a folder with the mail client an empty 
directory with the old name remains on the IMAP server file system.

root at mailserver:/data/mail1/user/bernd> ls -al
total 200
drwx------   8 cyrus    cyrus       7680 Apr 14 16:06 .
drwx------ 199 cyrus    cyrus       3584 Apr  7 18:32 ..
-rw-------   1 cyrus    cyrus       6697 Apr 14 15:35 980.
-rw-------   1 cyrus    cyrus       3210 Apr 14 15:39 981.

-rw-------   1 cyrus    cyrus       1012 Apr 14 16:13 cyrus.index

When renaming the renamed folder back to its origin name or creating a 
new folder with the same name the empty directory gets reused, so it's 
not very tragic. This does not happen when renaming or deleting folders 
with cyradm and the folders also don't show up when doing a list mailbox:

mailserver> lm user/bernd/*
user/bernd/Junk (\HasNoChildren)   user/bernd/Trash (\HasNoChildren)
user/bernd/Sent (\HasNoChildren)

This bug also exists with 2.2.0 alpha.
