title: GitLab "Reply-To" feature using Omnibus not working?
body: <p>We currently are running the latest version of GitLab (v8.0.1) which is installed using the Omnibus package and trying to enable the new "reply-to" feature but nothing is happening.</p>
  
  <p>We followed these instructions:
  <a href="http://doc.gitlab.com/ce/incoming_email/README.html" rel="nofollow">http://doc.gitlab.com/ce/incoming_email/README.html</a> (specifically the Gmail instructions).  We configured a new Gmail account with lesser-security and we also use the SMTP configuration.</p>
  
  <p>The email, when replied to, is being sent to the GMail account but from there nothing is happening.  The doco seems a little sparse but is GitLab supposed to pick that email up (via IMAP) and update the issue?  If so, nothing is happening.</p>
  
  <p>Our settings in the /etc/gitlab/gitlab.rb (and I had to add the "incoming-mail" section manually because it was not there) looks like this:</p>
  
  <pre><code># SMTP setup
  gitlab_rails['smtp_enable'] = true
  gitlab_rails['smtp_address'] = "aws"
  gitlab_rails['smtp_port'] = 587
  gitlab_rails['smtp_user_name'] = "AWSUSER"
  gitlab_rails['smtp_password'] = "AWSPASS"
  gitlab_rails['smtp_domain'] = "git.ourdomain.com"
  gitlab_rails['smtp_authentication'] = "login"
  gitlab_rails['smtp_enable_starttls_auto'] = true
  # gitlab_rails['smtp_tls'] = false
  # gitlab_rails['smtp_openssl_verify_mode'] = 'none' # Can be: 'none', 'peer', 'client_once', 'fail_if_no_peer_cert', see http://api.rubyonrails.org/classes/ActionMailer/Base.html
  # gitlab_rails['smtp_ca_path'] = "/etc/ssl/certs"
  # gitlab_rails['smtp_ca_file'] = "/etc/ssl/certs/ca-certificates.crt"
  
  # Configuration for Gmail / Google Apps, assumes mailbox gitlab-incoming@gmail.com
  gitlab_rails['incoming_email_enabled'] = true
  gitlab_rails['incoming_email_address'] = "gitlab+%{key}@ourdomain.com"
  gitlab_rails['incoming_email_email'] = "gitlab@ourdomain.com"
  gitlab_rails['incoming_email_password'] = "GLPASS"
  gitlab_rails['incoming_email_host'] = "imap.gmail.com"
  gitlab_rails['incoming_email_port'] = 993
  gitlab_rails['incoming_email_ssl'] = true
  gitlab_rails['incoming_email_start_tls'] = false
  gitlab_rails['incoming_email_mailbox_name'] = "inbox"
