2014-03-04 We've released a new extension: Amazon SES. It lets you send notifications to your customers using the Amazon Simple Email Service when you decide to use your own FROM address (@your-domain.com). An extra feature is that you can use the DKIM signatures in the emails. This solution greatly reduces the chances of emails sent by planyo being treated as spam. This was always rare but possible. Please see http://www.planyo.com/faq.php?q=188 for more details about this.
