Don't know about calendars. They are one of the better ones for multiple address - there's a limit on the number of a) domains) and b) email addresses you can reply from (but no limit on the number you receive from, with a catch-all). I think their different plans allow different numbers. The one what doesn't have any limits other than bandwidth is migadu. But they don't support second fact properly, last I looked.
