Danger, Will Robinson.  Personally, I avoid MailMangler like the
plague, and my blood pressure stays a low lower.  :-)

"mailhost" is a Sun-ism that isn't practical for us, since we
don't have a single central maildrop for EVERYONE.  It's not
difficult to adapt sendmail.subsidiary.cf, however.

In this setup, a single machine ("postoffice") serves some
number of clients with a shared mail spool.  /private/spool/mail
is replaced by a symbolic link to /clients/spool.mail on the
server, and is NFS-mounted by each client.  We *do not* run
sendmail -bd  on the clients.

The server's sendmail.cf lists all of the clients' names in its
Cw list (after its own name, of course).  While we have MX
records for each of the clients (pointing at the server),
the client sendmail configuration is tweaked so outgoing mail
appears to come from the mail server, so replies will go to
the right place.

server /etc/exports: (replace ... with colon-separated clients)

/clients/spool.mail	-access=...,root=...
/LocalLibrary/Images/People -ro,access=...

client fstab:  (folded for clarity)

postoffice:/clients/spool.mail /usr/spool/mail nfs rw,bg,timeo=14,
	mnttimeo=5,intr,nosuid,noquota 0 0
postoffice:/LocalLibrary/Images/People /LocalLibrary/Images/People
	 nfs ro,bg,timeo=14,mnttimeo=5,intr,nosuid,noquota 0 0

diffs between NeXT's sendmail.subsidiary.cf and my client
sendmail.cf attached below.  There are some minor bugfixes
and an expendable minor hack ("fidonet kludge"), and the
names have been changed to protect the guilty.  :-)
Note that I've effectively disabled the UUCP stuff; it takes
a bit more effort to get that stuff to work right.
WARNING: /etc/sendmail/sendmail.cf as shipped by NeXT is a
symbolic link.  Blow it away and replace it with a real file.
Do not modify the original sendmail.*.cf files; you may want to
refer to them later.

The stock answer to any "I can't get printing to work in 2.0"
questions is "upgrade to 2.1"--lots and lots of buggy code was
replaced in 2.1.  2.0 is *known* not to be able to talk to Suns.
