I'd say it's not fixable at all because the OoO reply usually doesn't 
quote any header lines.

Another example of patent trolling. :-(

maintain state? What do you mean by that?
It seems that read receipts *do* contain in-reply-to/references headers, 
so you could reuse these. Another method would be to allow read receipts 
up to a certain length at all. Would it make sense for spammers to 
disguise as read receipts? I'm not sure what most mail clients do with 
them, at least mine would just display it.
