Mailing module: mailing backend #51
Description
The distribution lists may be quite big, and contain thousands of e-mail addresses. The task of sending the e-mail shall be delegated to some external process working in the background in order not to block the threads responsible for serving the HTTP traffic.
Explore the available solutions, choose one and implement. The chosen solution might utilize Cron or a background process, and it must allow further integration with Rackspace Mailgun.
