I've always wondered why such systems don't use the Message-ID or
Reference headers - I know they aren't preserved by all mailers but I
think that having this info in the subject line is

a) visually disturbing (subjective)
b) I guess that the risk of a user modifying the subject line is the
same than finding a programm that doesn't to some extent honor the
headers i mentioned...

c) Personally whenever I find a mail that says please keep this in the
subject I delete that number on purpose...
