Description Jay Freeman 1999-07-07 16:06:26 UTC

If you do your standard  LIST "" *  command when you have
recursive symbolic links (which is actually common since
gnome likes to have the link ".gnome-desktop/Home
directory/" which points back to the home directory, which
of course has a .gnome-desktop in it...) imap continues
iterating deeper and deeper on a never ending quest to list
ALL the directories.  I noticed this when I was trying to
setup Outlook 2000 to use IMAP (although this should occur
in other versions as well, just never used them for IMAP
before) and requested a list of folders.

Comment 1 Cristian Gafton 1999-08-28 00:55:59 UTC

On my system imapd iterates over the recursive symlinks and outputs
them all until each dir listed reaches a size of PATH_MAX. It
certainly does not hang.

It is unclear to me if IMAP should really handle this case - I would
recommend asking the maintainers about a feature like this.
