Anybody know a good simple Unix mailer that will allow you to send mail from a script and add a really large number of names to the BCC list? I'm at a loss so far, and it seems like an easy problem. I've been too lazy to look up the SMTP protocol and write one myself, but this is getting to be a pain. And SMTP can't be that hard.
Alternately, one of the various generous folk who've talked about setting up a real mailing list for this might come through on that, but I'm not holding my breath :-)
