how to hide "To:" in mailing list

[cash_hr]

Hi!

I made some newsletter system and it's working great, except
one thing!

I don't want that is visible "To:" list when some users gets email.

Is that possible, and how?

Thanks in advance

Send it to yourself only in the TO: area, and BCC the rest.....

Am I doing something wrong?

I did it, but it doesn't work.

My variable look like this
$to="To:Jadranka Newsletter system \r\nBcc: [e-mail]".;

In Outlook and Netscape mail, BCC line is visible
