Help with Smartlist + Sender: root

["Marcelo E. Magallon" <mmagallo@efis.ucr.ac.cr>]

Hi,

	I'm having a problem setting up a mailing list with Smartlist. One
of the subscribers is being held hostage to an NT system ;-) and for some
reason it says "Sender: root@blah". Smartlist doesn't like it and rejects
mails. The point is he can't change the Sender line, so I have to change
Smartlist. The point... how?!?!? There's a daemon_bias setting, but I can't
figure out from rc.submit how that works... what does this mean:

	* 9876543210^0 something else

it says:

	* something
	* $$daemon_bias
	* something

and daemon_bias is just a number.

Any ideas? TIA,
