This is correct except the part about "undocumented".  See the MAIL Utility
Reference Manual, page MAIL-14.  (I didn't say it was easy to find, just
that it's documented.  :-)

This logical name actually operates as a bit mask with the following meanings:

    1 - this node is part of a homogeneous cluster, i.e., MAIL bypasses
        using DECnet to reach other nodes in the cluster, and just writes
        to the recipients local MAIL file.

    2 - directs MAIL to notify a user logged in on any node of MAIL arriving
        on any node in the cluster (almost always used with 1)

    4 - directs MAIL to include the time the message was delivered in the
        announcement.

1 and 2 are of interest only in (homogeneous) clusters;  4 is of interest
on any VAX.  The example above sets all three flags on.

Why this information isn't in either the Guide to VAXclusters, or the
System Management Guide, or both is beyond me.
