I think this thread

http://groups.google.co.uk/groups?selm=yeb4resysb1.fsf%40xpc21.ast.cam.ac.uk

on gnu.emacs.help might help you (it was me asking the same question not so
long ago!).

You mean that you want to put the actual addresses in the BCC field, then
just have some descriptive string in the To field, yes?

If so, I think the short answer to your question is:

(setq send-mail-function 'smtpmail-send-it
      message-send-mail-function 'smtpmail-send-it
      smtpmail-default-smtp-server "your.mail.server.machine"
      mail-use-rfc822 t)

Then you can use strings like:

To: undisclosed recipients:;
BCC: real1@address.com, ...

(note the closing ":;") in the To: field.
