This doesn't look like a relevant test. I have an account on a box on an
ISP which uses Postini, and the use of couriertls from the CLI, as quoted
below (w.o. addcr), hangs. However if I turn on ESMTP_USE_STARTTLS in
courierd and actually send an email to the account, it goes through, and
includes the following header:
Received: from source ([192.207.27.55]) (using TLSv1) by
exprod6mx93.postini.com ([64.18.5.10]) with SMTP;
Thu, 16 Dec 2004 12:20:32 EST
So a) the CLI couriertls test doesn't detect the problem, and b) the problem
isn't universal to all Postini mail servers. They may have fixed it, and I
have no way of knowing without turning ESMTP_USE_STARTTLS back on and
waiting for customers to complain.
