Mailing List management questions (probably RTFM, but hey...)

So...is there a mailing list manager that can receive an attached file, HOLD the attachment in an archive and send only a message saying "A new attached file is available in the archive"?

As well, is there a good way for putting a different-every-time message at the start of a digest - one that'll be manually compiled and probably be the last message to be written, just before the digest goes out?

Thanks!
