Yeah, what the others said; a mail list program (sorta like this mail list
that we're all using!)

You will swamp your mail server for one, and the messages won't go anywhere.
When you send a message with an attachment, the attachment is encoded to
MIME format which adds about 25% overhead to the size, so a 10 MB message
will expand to a 12.5 MB message and will bounce.  Not what you want.  It it
was me, I'd put up an ftp server and send a URL out to everybody and let
them download the files themselves rather than making your mail server do
wind sprints...
