[Evolution] threading by subject

[Eric Newman <enewman ati com>]

When threading by subject (because the In-Reply-To header is not
present), could you put the new messages to be threaded under the most
recent message with a matching subject? I keep getting emails with
identical subjects to mails that I got a month ago, and when people
reply to them, Evo threads them under the old ones.

Thanks,
Eric
