Hi Adrian.

To summarize the issue wrt threading (root and sub in the same folder where threading ahs been turned on):

Irrespective of whether the messages are from
GM -> GM account or
GM -> Outise Account or
Outside Account -> GM Account

the following persists :

(1) : If the root message is not originated by the email account owner, with folder level threading On, the threading is proper (as it should be).

(2) : If the root message is originated by the email account owner, with folder level threading turned On, then the threading starts from the reply to the root message.

(1) and (2) combined means that in any case, the threading always starts from the message "which is the first recd message of the thread in the account". If this "First Recd Message" happens to be the root message then everything seems fine but in case it is not (when the root is owned by the account owner) then the Threading actually breaks.

I hope that i have expressed the scenario clearly. GM -> GM is on the same server using the same sendmail wrapper (courier mta).

Could this be fixed?

Thnx
Anup
