Because that's not what IMAP flags are. They're individual annotations to a message, not a single annotation - as all the flags and keywords combined. Clearly if a client said "STORE FLAGS (\Answered)" "STORE FLAGS (+FOOBaz)" they wouldn't care, but if they said: STORE +FLAGS (\Answered) STORE +FLAGS (+FOOBaz) they really mean for both of those flags to be stored. Consider an IMAP agent that periodically marks messages with the "Junk" keyword. Suddenly those flags disappear- but the message is no longer \Recent so that clients remove the junk-status. If someone leaves their Thunderbird all day, but periodically opens with Eudora, they've lost their junk-scanning abilities. Of course: Thunderbird _happened_ to think that this was a possibility and stopped using \Recent and instead uses "NonJunk" now- but are all applications supposed to be so forward-leaning when rigorous testing suggests that they need not be? -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/
