There is no way to determine if *IMAP flags* have changed for a message without downloading all information about a message - which defeats the whole purpose of caching. This is a limitation with the current c-client library - the only way we can get flag information is multiple imap_search calls (which queries the entire mailbox 4 times to get the information needed), the imap_fetchstructure call (which returns all the information we are caching - not to mention the extremely inefficient way this function hits the IMAP server which won't be discussed here), or the imap_fetchheader call (why a fetch header call returns flag information is beyond me...). So we only update flag information when a message is first inserted into the cache or if the flag change is done via IMP/DIMP/MIMP. michael -- ___________________________________ Michael Slusarz [EMAIL PROTECTED] -- IMP mailing list - Join the hunt: http://horde.org/bounties/#imp Frequently Asked Questions: http://horde.org/faq/ To unsubscribe, mail: [EMAIL PROTECTED]
