[Dovecot] Custom Flags

[qmail at top-consulting.net]

I have modified my delivery agent to deposit files in my Maildir  
already containing custom flags.

For example, x is appended for files that are sent from local users, y  
is for e-mails from Contacts and z is for e-mails from Whitelisted  
sources.

A file will thus be delivered in the Maildir and be called something  
like: filename:2,yz

Also in the Maildir I created a file called dovecot-keywords and have  
added these 3 flags in there as so:

#cat dovecot-keywords
23 Local
24 InContacts
25 Whitelisted

I went ahead and erased all the dovecot-uid* dovecot.index* files but  
Dovecot won't recognize the flags - furthermore, it labels z as  
'unknown-25'! - for both old messages or new messages. Here is a bit  
of IMAP conversation:

a02 select inbox

* FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted )
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft  
unknown-25 Whitelisted  \*)] Flags permitted.



a03 SEARCH KEYWORD Whitelisted

* SEARCH
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25  
Whitelisted  Whitelisted)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft  
unknown-25 Whitelisted  Whitelisted \*)] Flags permitted.
a03 OK Search completed (0.004 secs).



a04 SEARCH KEYWORD unknown-25

* SEARCH
a04 OK Search completed (0.004 secs).


I know for sure there are files with the z letter in their name in the  
Inbox. What is going wrong ?
