No, you only need to disable it for hosts which "lie" about their TLS
capabilities.

Leave STARTTLS enabled for esmtp and only define exceptions in esmtproutes
like this:

badtls.com:badtls.com,25/SECURITY=NONE

this tells Courier to refuse to use STARTTLS with a domain regardless of
what the host claims to support.  You can use grep or monitor your
postmaster account for delays to determine when STARTTLS errors are taking
place.  Once the line is added, the message should go through successfully
on the next delivery attempt.  Or you could use "mailq" to identify the
message and "courier flush <messageid>" to force a reattempt on delivery.
