  I've had sites report that even going Solaris to Solaris using the
Solaris propietary lockd stuff, they still can get trashed mailboxes.
Locking of any kind over NFS just isn't reliable.

  Use IMAP as an alternative.  Set up your mail server as a IMAP server,
and use Pine, Simeon (www.esys.ca), or Netscape 4 on your clients.
