Are you using Sendmail? Some MTAs (notably sSMTP) support a

the genericstable, but i haven't used one on my Sendmail setups.
I finally figured out the correct incantation to get most of
genericstable working lastnight. The real killer is that it only works
if your message is sent with no FROM: designation. Like this:
echo "Test message" | sendmail [EMAIL PROTECTED]
When you do that you get something that looks like this:

Bcc:

So you can still see where it originated from, but anybody responding to
it gets a real email address. Now I just need to figure out how to get a
subject to the message... and a few other niceties.
As to clients and command lines, nail (a command-line mail client that
can do MIME) supports a -r option to specify From. As you're running
jobs as root, you could also do
Cool. That's what I was looking for, and kind of expected to find in a
command line client. Google wasn't much help though... I'll have to look
into this.
# su user -c 'fortune `# or other commands` |
mail -s "example message `date +%s`" [EMAIL PROTECTED]'
(I.e., the command inside the 'quotes' is executed as "user").
(And `# this` or $(# this) is the best i've come up with for bash
in-line comments).
Doh! I should have thought of using su... Damn that was dumb.
