So in this case the mistake is that of gmail webclient. Because: Have a discussion with someone on say "Bugs in the code". Now if your mailer justs looks at subjects to thread then two different mails with subjects "Bugs in the code" (and their subsequent replies) will be clubbed which is clearly undesirable. A real mailer a la mutt for example will thread mails based of message id's and this will solve this otherwise problem of mind reading. What is assumed is a bit of consideration from the replier. A new message should be started as a new message not as a reply to an old message with a changed subject. Regards ppk
