An unrelated netiquette point:
The email of mine that you are quoting was a private reply of mine
to a private message of yours.
Generally, you should ask permission from someone if you're going to
quote from their private email in a message on a public forum.
You did not ask me first before you quoted from my private reply.
I'm ... annoyed ... that you did not ask. In the future, please do so.
