Hi Sun-Managers,
My original question:
> I'm having some problems in configuring a Sparc 20 (Solaris 2.4) to work as
> a mail client of a Sparc 2 (SunOS 4.1.1B). The problem is that the Sparc 20
> tries to deliver local mail instead of forwarding the mail to the Sparc 2 for
> delivery. Non-local mails work fine: SP20 finds out that the SP2 is the
> mailhost and forwards the mail to it for delivery.
>
> Summary of the configuration:
>
> - Sparc 2: mailhost (NIS), SunOS 4.1.1B, local directory /var/spool/mail
> - Sparc 20: Solaris 2.4, sees the correct machine as mailhost from NIS,
> /var/mail is a link to /netmail/mail
> (automounter), using standard subsidiary.cf as
> sendmail.cf with the following differences:
>
> Line in subsidiary.cf Line in sendmail.cf
>
> Lmmaildomain # Lmmaildomain
> Dj$w.$m Dj$w

I've implemented Jochen Bern's solution: the easiest. Since
it worked, and worked well, I have to be honest: I didn't tried the
other solutions.
################# Jochen Bern's solution #####################
Drop SUN endmail Setups. Here's what I use:
###
### SENDMAIL CONFIGURATION FILE
###
### This is the sendmail.cf for a client who can make a TCP connection
### to a mail server. No local mail happens here, everything is sent to
### the server. Should work for just about any version of sendmail,
### i.e. doesn't use any e.g. Sun-specific features. Of coure, all
### userids on the client must also be known on the server, either as
### real userids or as aliases. Only the first section below should
### need any changes for a particular installation.
###
### Note that as opposed to the broken OR option in the sendmail.cf
### that Sun delivers, this configuration WILL queue mail on the client
### if it can't connect to the server. This means that the queue must
### be checked periodically, either by running sendmail in the normal
### daemon mode (e.g. /usr/lib/sendmail -bd -q1h) or by running
### /usr/lib/sendmail -q from crontab at appropriate intervals. Running
### sendmail in daemon mode is probably preferrable, since doing so
### will also handle mail that is mis-addressed to user@client.

## LOCAL CONFIGURATION INFORMATION
## Local domain name.
## This should only be changed if the full name of your hosts is something
## other than host.frobozz.com.
DmUni-Trier.DE
## The official name of this host.
## This may need changing if your 'hostname' command gives the full name,
## or you have specified the full name in your hosts database, or sendmail
## uses the name server directly (in a "default" Sun installation, none of
## these apply). To test this, give the command (after this file is
## installed) /usr/lib/sendmail -bs, and look at he hostname displayed.
## If the domain name is duplicated, remove the '.$m' from the definition.
Dj$w
## The server host where everything gets forwarded to.
## This is the one thing that you MUST change. Do NOT use a generic name
## like 'mailhost' here, but rather the name of the server host that
## should be visible in external mail.
DRTI
## Optionally do client-specific "aliasing" of certain local names.
## If you don't want mail sent to e.g. user 'root' on the client to be
## delivered to the same user on the server, uncomment the CL and DL
## lines below after editing them appropriately.
## (May be useful if groups of clients are administered by different
## individuals, since such mail often concerns host-specific issues.)
# Local mail to these userids...
#CLroot Postmaster MAILER-DAEMON
# ...will be delivered to this userid on the server
#DLsome-lsa
## GENERAL CONFIGURATION INFORMATION
## Stuff here is required and reflects some policy decisions.
## SMTP login message.

## Format of a sender's address; use full name.
Dq$x <$g>
## Version of this .cf file.
