Comment 2 for bug 1073520

Hi James

I've fixed 1), 2), 3) and 4). I didn't address 5 since I don't think it belongs to this charm. Ideally, instance running this charm will be end-point for all email. Relayhost would be used only for delivering email to 'out of cloud' services. Reason why I say that is cause this charm deploys imap and pop3 services, suggesting that is it end point.
