title: Create email server with SilverStripe
body: <p>I know I can send emails from a custom domain in Silverstripe like from 'user1@mydomain.org', but I am wondering is there a way to create email server using Silverstripe which will allow me to register new email addresses for users using the Silverstripe UI.</p>
  <p><em><strong>Idea is to create a domain and allow registering the users under the latter domain and also have some kind of a web client (or through outlook), so that the users can check their emails. Basically setup gmail (but with our custom domain) inside Silverstripe</strong></em></p>
  <p>I feel like this is a stretch, but I have 0 experience in Silverstripe and would like input on this from someone who knows more about this CMS.</p>
  <p>Thanks!</p>
