This week the OpenShift team announced support for connecting to externally hosted email services (POP, IMAP, and SMTP). What this means for developers is that you can establish a connection from your app to your own email server or one of the popular public email services like Gmail or YahooMail. For users deploying popular blogging or wiki software (Drupal, Joomla, MediaWiki, WordPress, etc.) on OpenShift, you can also take advantage of this new feature by altering the email settings of the software to point to the appropriate email service.
For those of us that don’t already have access to an email service, you can sign up for an account with something like Dyn Standard SMTP or simply search for ‘email relay service’ to get an idea of what options are out there.
The specific ports that have been enabled to support this are as follows:
If you’re unable to make a connection to one of these services, make sure that your email provider allows authenticated connections from Amazon AWS EC2 hosts.
