title: Ad-hoc distribution through email
body: <p>On <a href="https://developer.apple.com/programs/ios/distribute.html" rel="noreferrer">this site</a>, I found that you can distribute through email:</p>
  <blockquote>
  <p><strong>Ad Hoc Distribution</strong></p>
  <p>With Ad Hoc distribution you can share your app with up to 100 other iPad, iPhone, or iPod touch users. <em><strong>Through
  email</strong></em> or by posting it to a server, users can download and install
  your app.</p>
  </blockquote>
  <p>I cannot find any instructions on how to do this. Since it says, &quot;through email <strong>or</strong> by posting it to a server&quot;, I am expecting to be able to send an email with the needed file(s) attached without using a server. Is this possible?</p>
  <p>I tried emailing myself the .ipa that results from archiving the app in Xcode, but it says:</p>
  <blockquote>
  <p>Mail cannot open this attachment.</p>
  </blockquote>
  <p>How can I distribute an app through email if the Mail app doesn't know what to do with it?</p>
