Put the mail disk on System C, make it an NFS server for mail only, as well
as a mail server. Make it an NIS client or NIS slave server (less preferable
to you, I suspect). Make an host alias for system C in hosts map as
'mailhost'. [ A hard mount and a soft mount are both just NFS mounts, btw]
Why not make the DNS primary your NIS master [system C], and system B can be
mail, DNS secondary and NIS slave server.

There, I think that's it. A distributed system.
You then have:

System A	general purpose NFS file server. Why not make this an NIS
		slave server, too?
System B	NIS master server. DNS primary server.
System C	DNS, NIS and mail server.
