The issue here seems also, that dovecot sends a list of keywords after a 'select mailbox' based on what it finds in the index file. And in my case sometimes the keyword list in the index file differs from the keywords set in the respective mailbox' mails. If there is no way to alter this list of keywords - is there any API or script interface (like lua) with which one could alter the IMAP responses dovecot is sending? For a selcet inbox the server answers with FLAGS and PERMANENTFLAGS - might there be a way to alter the PREMANENTFLAGS response? Example: b select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. -- Cheers spi

There is no supported way to manage keywords at this moment. Modifying the actual IMAP responses is very hard. Aki
