Please look into /etc/rc[0-3].d directory.  There will be files named
S??smtpd and K??smtpd (?? is replaced with some two-digit numbers).  The
S??smtpd file is a shell script that starts smtpd and K??smtpd kills
smtpd.  These scripts are executed by /etc/rc? process when the system
starts up and shuts down.  You must change these scripts to start/stop
sendmail.  If you have S??smtpd and K??smtpd files that handle sendmail
in your /usr/ucblib directory, just copy them into appropriate
/etc/rc?.d directories.  Even if you don't have such replacement files,
the modification is trivial.

If you are using default /bin/mail and /bin/rmail, you must change
/etc/mail/mailsurr with the one supplied in /usr/ucblib directory.  If
you copyed /usr/ucblib/binmail to /bin/mail and /usr/ucblib/rmail to
/bin/rmail, you don't have to worry about AT&T mail system.

The Apparently-To: header field is added by sendmail.  Your Mail User
Agent, such as mailx, has responsibility to set To: field correctly.
Don't use /bin/mail directly, because it does not add To: field.

mailx uses /usr/bin/rmail for mail delivery.  If you replaced
/usr/bin/rmail with /usr/ucblib/binrmail, it will not cause problems.
If it does not work, add a line

	set sendmail=/usr/ucblib/sendmail

in the file /etc/mail/mailx.rc.  (I never used mailx with
sendmail-on-SVR4 configuration, so I'm not sure.  Please try it out and
let me know if it does not solve the problem.)

> 5.  Any general hints/comments on using sendmail on SVR4 are appreciated.

I recommend to use Smail 3.1.  It works fine on SVR4.
