Can smartlist use bcc instead of "to"

I'm just trying out smartlist, and I've hit what appears to be a roadblock. Perhaps I didn't RTFM enough times. :-) I don't want all the members on the list to know the e-mail addresses of everyone else on the list. However, when I send a test message to the list, each list member gets a message with the entire list's e-mail addresses in the "Resent-to" header. Is it possible to get smartlist to send out the messages using the "bcc" header? Or is there some other way to keep the addresses of the list members private? Thanks, --- Wade
