If the mbox in question has a message *appended* to it then mutt regards this as OK and will not output the error. It detects an append by looking to see if the 'message separator' before the appended message is exactly where the end-of-file was previously. I suspect my MTA doesn't agree exactly with mutt about where the 'message separator' is. I need to play some more! :-) -- Chris Green
