I can send and receive emails to individuals but not to my contact list that I've been using for years. I've tried other lists and making up a new list of two contacts but the same thing happens. Yesterday, I solved the problem by opening in 'safe mode' but this didn't work today. I get this message when I try: Broken River Potters <"Broken River Potters"> <> is not a valid e-mail address because it is not of the form user@host. You must correct it before sending the e-mail.
