A good technical discussion of my concerns can be found here.
The exchange and the personal nature of it got to me; I decided to stop being whiny and start being cold, calm, and officious. From now on, when I get this sort of email, I simply will redirect it to a special email account I have set up. The account has an auto-responder which will sned back the following email:
This is an automated message.
You recently sent an email to my-domain.com as part of a large distribution list using Carbon Copies, or CC: for the distribution list. As a result, each person on the list can see the entire distribution list, and each persons email address is available to all of the persons on the list.
In order to reduce SPAM and abuse of such lists, as well as to preserve privacy, I would prefer not to be included in mailings from persons using this form of distribution.
If you are able to switch over to an anonymous form of bulk emailing (such as using BCC: or Blind Carbon Copy) I would be most appreciative.
There is a good discussion of my concerns with regard to this practice here: http://www.cs.rutgers.edu/~watrous/bcc-for-privacy.html
If you are not able to make this change, or would prefer not to, kindly remove all my-domain.com email addresses from your distibution list; I would prefer not to receive these emails.
