Hi Folks!
I have a linux (RedHat 8.0) box running at home and want to access the
mailserver from my university (Innsbruck,Austria), but my linux-boxes
imap client fails to SELECT subfolders. From my Windows Computer running
Mozilla it is possible to access all submailfolders. Any ideas how to
get it working?
Here is some detailed information:
Systems installed
1) On my RedHat Linux box the UW imap2001a is installed. It ships with
RedHat 8.0
It keeps the inbox in /var/spool/mail/UID where UID is the user-id of
the logged-in user
and mailfolders in ~/mail/foldername e.g. ~/mail/Sent
and subfolders in ~/mail/folder/foldername e.g. ~/mail/Archiv/Compaq
2) My university seems to be running imap-2002.RC2b-mbx-ssl on their
mail servers, also from the UW, I suppose.
It keeps the inbox in ~/INBOX
and mailfolders in ~/Mail/foldername e.g. ~/Mail/Sent, ~/Mail/junkmail
and subfolders in ~/Mail/folder/foldername e.g. ~/Mail/Archiv/Compaq
(listings of the directories with full details see below "4")
3) The problem encountered:
I use a programme called "mailsync" that uses the c-client.h file from
my system (I compile it against this file). This programme uses the
c-client.h to access 2 (or more) mailboxes on (different) imap-servers
with the imap protocol to keep the mailboxes in synch (by performing
EXPUNGE operations if a message has been expunged on either server, VERY
useful when having only a dial-up connection).
With the local c-client installation I can happily access the INBOX on
the remote University Innsbruck (uibk) server and
"top-level-mailfolders" (like ~/Mail/junkmail) but not submailfolders
(like ~/Mail/Archiv/Compaq). The imap-client sees these folders (the
mailsync programme can list all existing mailboxes) but thinks they are
EMPTY, because it seems unable to open them with the SELECT function.
Here's a log from my console on the linux box at home:
The programme gives me errors like:
---

4) the structure of my university mailserver:
-------------- directory structure -------------
The directory '~'

Does anybody know what could be the reason for this - apparently
c-client - problem?
Thank you, Greeinx
