I don't know about good free alternative with support etc. That's also why I'm paying ~50$/year for a mailserver hosting - I've moved from gmail to just that and so far I'm quite happy. Maybe someday I will spin up my mailserver also, but for now this is quite good balance between convenience & price for me.
