Newsgroup -

I don't know if this is the right newsgroup to ask this question in, but I
don't see a GWIA/GW Client developer support group.

What does the GW Client (GW65) use to trigger if a message is a reply to
another one in the threaded discussion view? I'm writing a mail gateway for
our helpdesk application which sends messages to GWIA every time an incident
is touched, and I'd like to have all of the messages for incident
modification appear as a thread under the "incident created" email.
