Rackspace has acquired Mailgun. Mailgun simplifies email integration into websites and applications. Developers can easily use their powerful set of APIs to send, receive, and track email effortlessly – without managing an email server or becoming an expert in email setup, operations and deliverability. Mailgun is built for developers. It has server-side MIME assembly, which means that no libraries are required. The service allows you to receive event notifications via a webhook, and everything is priced to scale as you scale.
Mailgun also allows you to track your email responses and parse them for data. You can then use that data to take an action. For example, you can parse an attachment of a video from a mobile user to an email address and post that video on a website or share it on social networks. Developers can also track opens, unsubscribes, bounces, and complaints using the API. Mailgun makes sure your email gets to the end user's inbox.
Mailgun really shines when using it via the API, but if you are trying to move a legacy application to the cloud you can configure your mail transfer agent (MTA) to relay through Mailgun's service. To set this up in Postfix, add the following settings to /etc/postfix/main.cf:
mydestination = localhost.localdomain, localhost relayhost = smtp.mailgun.org smtp_sasl_auth_enable = yes smtp_sasl_password_maps = static:firstname.lastname@example.org:password smtp_sasl_security_options = noanonymous
You will need to create a mailbox for this as your control panel credentials will not work for relaying mail.
Once you're ready to use the API to send a message, you can add this to your Ruby application:
