|
Called by mailbox_postcreation() after a mailbox has been
|
|
created. Immediately returns, unless configuration indicates
|
|
that one or more sub-folders should be created.
|
|
|
|
Triggers E_USER_ERROR if configuration error is detected.
|
|
|
|
If IMAP login fails, the problem is logged to the system log
|
|
(such as /var/log/httpd/error_log), and the function returns
|
|
FALSE.
|
|
|
|
Returns FALSE on all other errors, or TRUE if everything
|
|
succeeds.
|
|
|
|
Doesn't clean up, if only some of the folders could be
|
|
created.
