It uses the In-Reply-To: header if that is available. If not, it uses
the References: header if that is available. If these are not available,
it looks for previous messages with the same subject header. Matches based
on the subject are listed as "maybe" replies.
If the linkquotes option is used, it will also search the message bodies
of the previous searchbackmsgnum (default = 500) messages for text that
looks like it is being quoted in the current message. If it finds one or more
prior messages with such text matches, it will treat the one with the longest
match as the message being replied to. The exact algorithms for deciding what
is quoted text are a bit complex. These matches override the In-Reply-To:
and References: header info (this rule may deserve further thought).
