Mail delivery and MX records are easy.  But once mail is received, you have
to get it to user's mail boxes, and users have to gain access to the
repository.  The repository should be 'highly available' in some fashion:
partitioned storage units, redundant storage, replicated storage, backup
storage, or whatever.  I believe that is the hard bit:  making the
repository 'highly available'.

How do people do it?
