Remove email configuration

This has a separate guide so link to that.

The guide here just leaves a half-installed MTA so its bound to cause trouble. We can include a brief guide in the installing MTA docs if desired.

+Full configuration for an MTA is beyond the scope of this document -- see the guide for [configuring the Exim4 or Postfix MTAs]({{ site.baseurl }}docs/installing/email/).
 
-### Minimal
-
-If you just want to get the tests to pass, you will at a minimum need to allow
-sending emails via a `sendmail` command (a requirement met, for example, with
-`apt-get install exim4`).
-
-### Detailed
-
-When an authority receives an email, the email's `reply-to` field is a magic
-address which is parsed and consumed by the Rails app.
-
-To receive such email in a production setup, you will need to configure your
-MTA to pipe incoming emails to the Alaveteli script `script/mailin`. Therefore,
-you will need to configure your MTA to accept emails to magic addresses, and to
-pipe such emails to this script.
-
-Magic email addresses are of the form:
-
-    <foi+request-3-691c8388@example.com>
-
-The respective parts of this address are controlled with options in
-`config/general.yml`, thus:
-
-    INCOMING_EMAIL_PREFIX = 'foi+'
-    INCOMING_EMAIL_DOMAIN = 'example.com'
-
-When you set up your MTA, if there is some error inside Rails, the
-email is returned with an exit code 75, which for Exim at least means the MTA
-will try again later. Additionally, a stacktrace is emailed to `CONTACT_EMAIL`.
-
-See [this example]({{ site.baseurl }}docs/installing/email/) for a possible configuration for Exim (>=1.9).
-
-A well-configured installation of this code will have had Exim make
-a backup copy of the email in a separate mailbox, just in case.
+Note that in development mode mail is handled by [`mailcatcher`](http://mailcatcher.me/) by default so
+that you can see the mails in a browser. Start mailcatcher by running `bundle exec mailcatcher` in the application directory.
