+Cyrus IMAP autosievefolder patch
+----------------------------------
+
+NOTE : This patch has been created at the University of Athens. For more info, as well
+as more patches on Cyrus IMAPD server, please visit http://email.uoa.gr
+
+
+ When the lmtpd daemon receives an email message prior to delivering it to the
+INBOX folder of the user, checks if the user has specified sieve filters. If the
+user has specified sieve filters the filters are evaluated. If the message matches
+any of the filters the action that is specified in the filter is executed. If the action
+is FileInto it is stored in the subfolder specified in the filter. If the
+subfolder doesn't exist then the message is sent to the INBOX folder of the user.
+
+ With this patch if the folder doesn't exist AND the name of the subfolder is
+specified in the autosievefolders option, OR the anysievefolder is set to
+yes in the cyrus-imap configuration file then the subfolder is created and the mail
+is stored there.
+
+
+Check the following options of the imapd.conf file
+==================================================
+
+* anysievefolder : It must be "yes" in order to permit the autocreation of any
+INBOX subfolder requested by a sieve filter, through the "fileinto" action. (default = no)
+* autosievefolders : It is a "|" separated list of subfolders of INBOX that will be
+automatically created, if requested by a sieve filter, through the "fileinto"
+action. (default = null)
+ i.e. autosievefolders: Junk | Spam
+
+WARNING: anysievefolder, takes precedence over autosievefolders . Which means that if
+anysievefolder is set to "yes", cyrus will create any INBOX subfolder requested, no-matter what the value of autosievefolders is.
+
+
+Things to be done
+=================
+
+1. Support cyrus wildcards in the autosievefolders option.
+
+
+For more information and updates please visit http://email.uoa.gr/projects/cyrus/autosievefolder
