If the mail client uses the Subject header to identify threads, that's
a defect in the mail client.

What *does* break threading is using a mail client which doesn't set
the In-Reply-To or References headers when sending a reply.

For more details, see RFC 2822:

 Even adding some words to the subject line is
 usually considered as a change, so it
 creates a new thread.

Hi,

it depends on your software, many email clients and online archives know about 
 use email header lines to signify the relationships regardless of the subject 
line. Other email clients ignore all that and simply go by the strict subject 
line or their own fuzzy intelligence sorting method (eg gmail?).

see for example
