  //
  // To avoid this, you should configure a second domain in the same way you
  // have the primary domain configured (e.g., point it at the same machine and
  // set up the same vhost rules) and provide it here. For instance, if your
  // primary install is on "http://www.phabricator-example.com/", you could
  // configure "http://www.phabricator-files.com/" and specify the entire
  // domain (with protocol) here. This will enforce that files are
  // served only from the alternate domain. Ideally, you should use a
  // completely separate domain name rather than just a different subdomain.

// -- Email ----------------------------------------------------------------- //

  // Some Phabricator tools send email notifications, e.g. when Differential
  // revisions are updated or Maniphest tasks are changed. These options allow
  // you to configure how email is delivered.

  // You can test your mail setup by going to "MetaMTA" in the web interface,

  // When a message is sent to multiple recipients (for example, several

  // everyone (e.g., "To: alincoln, usgrant, htaft") or separate emails to each
  // user (e.g., "To: alincoln", "To: usgrant", "To: htaft"). The major
  // advantages and disadvantages of each approach are:
  //
  //   - One mail to everyone:
  //     - Recipients can see To/Cc at a glance.
  //     - If you use mailing lists, you won't get duplicate mail if you're
  //       a normal recipient and also Cc'd on a mailing list.
  //     - Getting threading to work properly is harder, and probably requires
  //       making mail less useful by turning off options.
  //     - Sometimes people will "Reply All" and everyone will get two mails,
  //       one from the user and one from Phabricator turning their mail into
  //       a comment.
  //     - Not supported with a private reply-to address.
  //   - One mail to each user:
  //     - Recipients need to look in the mail body to see To/Cc.
  //     - If you use mailing lists, recipients may sometimes get duplicate
  //       mail.
  //     - Getting threading to work properly is easier, and threading settings
  //       can be customzied by each user.
  //     - "Reply All" no longer spams all other users.
  //     - Required if private reply-to addresses are configured.
  //
  // In the code, splitting one outbound email into one-per-recipient is
  // sometimes referred to as "multiplexing".
  'metamta.one-mail-per-recipient'  => true,

  // When a user takes an action which generates an email notification (like
  // commenting on a Differential revision), Phabricator can either send that
  // mail "From" the user's email address (like "alincoln@logcabin.com") or
  // "From" the 'metamta.default-address' address. The user experience is
  // generally better if Phabricator uses the user's real address as the "From"
  // since the messages are easier to organize when they appear in mail clients,
  // but this will only work if the server is authorized to send email on behalf
  // of the "From" domain. Practically, this means:
  //    - If you are doing an install for Example Corp and all the users will
  //      have corporate @corp.example.com addresses and any hosts Phabricator
  //      is running on are authorized to send email from corp.example.com,
  //      you can enable this to make the user experience a little better.
  //    - If you are doing an install for an open source project and your
  //      users will be registering via Facebook and using personal email
  //      addresses, you MUST NOT enable this or virtually all of your outgoing
  //      email will vanish into SFP blackholes.
  //    - If your install is anything else, you're much safer leaving this

  //      mostly never arrive.
