This is generally a bad idea to do from a Web script. It may take tens of
minutes to deliver all of them to the local mail server just to queue the
messages, depending on how you do it.

The return-path header is generated by the mail server to which you relay
you messages. So, whatever you put there is overriden by the mail server.
If you only use Windows, the only way I know to set the return-path is to
send the messages directly to a SMTP server. You may want to check these
PHP classes that can be used in combination to set the Return-Path header
as you want:

What you need to do is to use PHP standalone CGI executable and run a PHP
script that will do the delivery.
Anyway, if you were using Unix, I would recommend a ezmlm/qmail solution if
all users are going to get the same message. Since you are running
Windows, I don't know what would be the best tools to use, because the
simple solution of of relaying that many messages to a SMTP server is not
very efficient.
