Hello, due to a very large number of users we had to change the cyrus code to hide namespaces (in the command namespace). We have added two options (list_on_user_space and list_on_shared_space) without options, the namespace command returns the following result: . namespace * NAMESPACE (("INBOX." ".")) (("User." ".")) (("" ".")) . OK Completed Then with the following options: list_on_shared_space: 0 list_on_user_space: 0 . namespace * NAMESPACE (("INBOX." ".")) NIL NIL . OK Completed There is no impact to users admins. It is possible that I provide a patch. Christophe. -----Message d'origine----- De : info-cyrus-bounces+christophe.zbierski=atosorigin.com@xxxxxxxxxxxxxxxxxxxx [mailto:info-cyrus-bounces+christophe.zbierski=atosorigin.com@xxxxxxxxxxxxxxxxxxxx] De la part de John Madden Envoyé : lundi 25 juillet 2011 16:45 À : Cyrus User's Mailing List Objet : disabling shared namespace Our issues with cpu usage with very large mailbox databases (4 million mailboxes) persist and I started poking at source code this morning, finally having time to look for a fix again. I originally wrote about this some time ago: http://comments.gmane.org/gmane.mail.imap.cyrus/32964 Again, we have no use for a shared mailbox namespace but there doesn't appear to be any way to easily disable it. Could it be as simple as just removing everything but NAMESPACE_INBOX from the enum in imap/mboxname.h? In other words, if we change it to enum { NAMESPACE_INBOX = 0 }; will anything else break?
