Which HTTP server? the getFavicon method requests the favicon from each domain, so any one email provider only gets a single request for a favicon. It doesn't send all the contact info to any single server. So reading the code, say you have in your contact b@acme.com a@acme.com c@google.com The code makes a single request to acme.com (to get the favicon) and one to support.google.com to get that favicon (there's a special case for google to avoid getting the new doodle of the day). That's it. I don't really see how that's sharing contact details.
