what version of Sendmail ?

If it is the default with solaris 8 - then you should find a /etc/mail/sendmail.cf file - make a copy of it, vi the original and add the mail relay name in either the DH or DR line. Then insure that the start up script in /etc/rc2.d or /etc/rc3.d is removed. If you don't want the system to accept mail don't start Sendmail. Email will still go out to the relay.

Example:
# who I send unqualified names to (null means deliver locally)
DRsmtp.womnet.com

# who gets all local email traffic ($R has precedence for unqualified names)
DHsmtp.womnet.com

FYI - if your system is running sendmail and is connected to the internet (and not protected by a firewall) there is a possibility that a spammer can use your system as a relay. This is why you don't start sendmail on boot unless the system is the mail relay.

MAILER.CONF(5)						      BSD File Formats Manual						    MAILER.CONF(5)

NAME
mailer.conf -- configuration file for mailwrapper(8) DESCRIPTION
The file /etc/mailer.conf contains a series of lines of the form name program [arguments ...] The first word of each line is the name of a program invoking mailwrapper(8). (For example, on a typical system /usr/sbin/sendmail would be a symbolic link to mailwrapper(8), as would newaliases(1) and mailq(1). Thus, name might be ``sendmail'' or ``newaliases'' etc.) The second word of each line is the name of the program to actually execute when the first name is invoked. The further arguments, if any, are passed to the program, followed by the arguments mailwrapper(8) was called with. The file may also contain comment lines, denoted by a '#' mark in the first column of any line. The default mailer is postfix(1), which will also start by default (unless specifically disabled via an rc.conf(5) setting) so that locally generated mail can be delivered, if the ``sendmail'' setting in /etc/mailer.conf is set to ``/usr/libexec/postfix/sendmail''. FILES
/etc/mailer.conf EXAMPLES
This example shows how to set up mailer.conf to invoke the postfix(1) program: sendmail /usr/libexec/postfix/sendmail mailq /usr/libexec/postfix/sendmail newaliases /usr/libexec/postfix/sendmail This example shows the use of the mini-sendmail package from pkgsrc in place of postfix(1): # Send outgoing mail to a smart relay using mini-sendmail sendmail /usr/pkg/sbin/mini-sendmail -srelayhost send-mail /usr/pkg/sbin/mini-sendmail -srelayhost Note the use of additional arguments. SEE ALSO
mail(1), mailq(1), newaliases(1), postfix(1), mailwrapper(8) pkgsrc/mail/sendmail, pkgsrc/mail/mini_sendmail HISTORY
mailer.conf appeared in NetBSD 1.4. AUTHORS
Perry E. Metzger <perry@piermont.com> BUGS
The entire reason this program exists is a crock. Instead, a command for how to submit mail should be standardized, and all the ``behave differently if invoked with a different name'' behavior of things like mailq(1) should go away. BSD
