Right, because the "Replied" flag is set by a MUA on a delivered message 
that you have replied to, and that event does not propagate back to the 
sender in any way except for the reply itself.

I don't see an obvious solution but what you need to detect is the 
non-existence of any message with the same Thread-ID as something you 
sent AND is newer OR has a In-Reply-To or References header citing a 
message ID of a message you sent.

I think I would do that by way of a custom keyword, but I haven't 
thought it through completely. (and won't, because I'm mostly incapable 
of doing deadlines usefully.)
