I am trying to set up a sendmail configuration that will forward mail to
a decnet host.  A portion of the sendmail.cf is at the end of this
message.  Currently this config allows mailing to a decnet host using
two formats   decnet::user and user@decnet.DNET.  Would like to have
mail of the form  user@node be converted to node::user and use mail-11.

This sendmail.cf allows mail of the form node!user to be forwarded over
SMTP as usr@mail.  I believe this is handled by comparing the to node to
a list of smtp hosts(macro DS?).  There appears to be a similar setup
for decnet nodes(macro DZ?) and in rule 5 I added what I thought was a
line to determine that transport was handled by decnet.

This is my first endeavor into sendmail, other than adding new nodes to
our internal network.  I would appreciate email explaining what I am
missing.  Also looking for information on how to decipher the rules in
sendmail.cf files.  If anyone could forward a good description of these
innards, I would appreciate.

I will certainly summarize the responses I receive and when the problem
is resolved, will post the solution to the net.
