There is another alternative; 

The above broblems stem from the fact that the system can not find a
group of mail, either from the registry, or in the /etc/group (how
UNIX like) file.  

If no action is taken to create an /etc/group file, the system will
have an empty file.  There is an official and unofficial way to create
the file.

Officially, ether run a slave rgyd on the node or run llbd on the
node.  In a casual conversation with our system support engineer, it
was recommended that ALL nodes run llbd (not mandatory, but
recomended).  Once we started llbd on our nodes, all was well,
assuming that the mail spool directory is available.

Unofficially, you could copy the /etc/group file from the master rgyd
node.

Hope this helps;
