Can I have subfolders not appear under INBOX?¶
The altnamespace setting in
/etc/imapd.conf changes the way the
mailbox list is presented to users (including fileinto directives in
Sieve scripts). Instead of appearing as subfolders of INBOX,
altnamespace makes subfolders appear at the same level as INBOX. It does
not affect the internal storage nor the way the folders are presented
through cyradm. See imapd.conf(5) for more information.
