Ok I had a very strange email issue today. One of my clients tried sending to various email addresses and kept getting a bounce message with “None of your e-mail accounts could send to this recipient” error.
After some investigation a number of contacts had been setup to use “MAILTO” rather than “SMTP” (you can check this by double clicking on the contacts name) to resolve the issue I deleted the contact and typed them in, then doubled clicked on them to verify that it had defaulted to SMTP.
