I have prepared a new list in my address book of 36 addresses. I called it Signatures 2024. I tried to send the emails and it won't send and I have received a note "Invalid Recipient Address. Signatures 2024 is not a valid email address because it is not of the form user@host. You must correct it before sending." I have done similar many times in the past with success so do not know what to do. It is urgent that I get this email out. Regards Bevan Lawrence
