All Jelastic application servers allow you to send emails from the local web server, but we recommend that you integrate your scripts with a specialist transactional email provider. We don’t have any specific recommendations, but existing customers are using specialists including Mailjet, Sendgrid and Mandrill which all offer free tiers in their pricing plans.
Inbound email functionality (i.e. mailboxes) is currently outside of the scope of our LWS Jelastic PaaS. You can point your MX records to an external email service such as Google Apps, Outlook.com
