Avoid sending e-mails to many recipients "in clear"

This article was first written in June 2004 for the BeezNest technical

You should always avoid to send e-mails to many recipients at the same time with their address in the To: or Cc: field. The reason is that if you use Bcc:, any recipient will not be able to see other's e-mail address.

Why would you want that?

Because many viruses on the Internet these days know how to go into your e-mail archives and search for the e-mail addresses that you can see too.
