I have been sending mail and forwarding mail by putting address in BCC only. ( so no one gets some body else's e-mail address ) But all of sudden I can't send or forward e-mails without putting an address in the TO line. This has just started this month and it's not only me, a friend wrote to say she has the same problem. Is this something new I P s
