  • This is a security setting.  You cannot arbitrarily send email as though you were a different user.  This helps prevent email hacks.  Your code is enumerating through a user's unread emails.  For each one it is trying to send a new email.  That is not going to work.  I'm not even sure what you're trying to do as it looks like you're going to blast out emails to everyone in the inbox which is a clear case of spamming which we cannot support.  If you can clarify exactly what you're trying to do then we might be able to help you otherwise this looks like malicious code.

  • Ok, if you want to reply to the original sender then you'll use Reply and not Send.  Reply probably shouldn't give you any error.
