I switched back to Airmail on OS X last week as it was pretty obvious Mailbox was dead as there were 2 critical bugs regarding switch and images not loading that hadn&#x27;t been fixed in months. It&#x27;s a shame but that&#x27;s life.<p>I have to manually setup the rules&#x2F;filters for now but reading through some other clients in the app store they seem to be buggy. I used Airmail years ago before Mailbox and it was stable and has been since switching back.
