I use Mulberry 4.0.8 as my mail client, and it works well with
mix-format mailboxes through release 2006g. Beginning with release
2006h, Mulberry misclassifies subordinate mix-format mailboxes as
"containers". They are displayed using a folder icon in the server
pane (hierarchical list of mailboxes within server), and they cannot
be opened to view messages. That's just like filesystem directories
are treated. Only top-level mix-format mailboxes can be opened to
view messages.
I have included IMAP protocol traces from Mulberry for three UW IMAP
releases:
2006g - Mulberry works properly (server claims it is 2006f)
2006h - first release that causes problems in Mulberry
2007d - latest UW IMAP release
The mailbox structure is:
INBOX
a-a2-a3+a41
|
+a42
b
d+d2
|
+d3
KeepAwhile
Sent
Spam
All mailboxes are mix-format, except d is a filesystem
directory and d2 and d3 are mbx-format files within d.
To produce the protocol traces, I clicked on the "+" icons in the
Mulberry server pane to expand the hierarchical lists for the "a"
and "d" hierarchies.
On release 2006h and later a2, a3, a41 and a42 appear as folders and
cannot be opened in Mulberry to view messages. Other IMAP clients,
like Alpine and Thunderbird, appear to be unaffected.
Comments about the differences in server responses which are causing
problems in Mulberry would be appreciated.
Thanks,
