Yes, but postfix people will know how to do it :) - sorry for hijacking the

I must admit, I've not seen people do mail broadcasts from Cron before -

Well, we ended up using getting a Perl wizard to assist. We're now using a
perl script, pulling real Mail addresses from MySQL, and using a Perl Mail
module to submit the mail into the postfix queue. As this system hosts under
1000 mail addresses, we don't have to worry about message copies so much. If
this box was hosting a couple of thousand mailboxes, I'd say we'd have gone
with linking the broadcast message into their Inbox, to save mail delivery
routines and load.
At any rate, we've got what we need now. I thought I'd better be polite and
post the script we're now using, as someone else may find it useful:
