Is there a way to hide the mail recipients in the TO: field of the mail() function?
no. but you can use BCC: headers in the mail() function.
mail("", $subject, $message, "bcc:user1@host.com,user2@host.com\n");

uhm, yes, but useless,... you have to use variables for the bcc and that's harder...
I see the BCC is in the fourth argument there...where would the "FROM: suer@here.com\r\n"" then be placed?
