While we’re still at a pretty early pre-release version, we already do multiple accounts and unified inbox with ownCloud Mail: <a href="https:&#x2F;&#x2F;github.com&#x2F;owncloud&#x2F;mail" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;owncloud&#x2F;mail</a><p>If you do try it, please let us know of your feedback in the issue tracker! :)<p>(And that is, you can also run ownCloud with the Mail app locally. We’re working on improved caching.)
