I'm having a problem with dovecot and apple mail not always

doesn't do it. The mail is stored in Maildir format in the users
home directory. All the connections Apple Mail are done via IMAP.

Check with rawlog what happens when you're changing the message
flags? Does it send the STORE +flags \Seen commands immediately?

I'm not sure if I've had problems with seen flags. My other client is
Evolution, and it doesn't notice flag changes made by other clients
anyway, so I have to keep setting them there anyway..
