Sendmail uses a new delivery scheme since version 8.12:
1.) "/usr/sbin/sendmail" is not setuid root anymore. Instead of perfoming
the actual mail delivery it will only connect to the SMTP port on
the local machine via the loopback interface and pass the e-mail to
the sendmail daemon.
2.) The sendmail daemon is still running as user root and will deliver
You could therefore simply run a sendmail daemon by putting the following
settings in "/etc/rc.conf":
The default configuration "netbsd-proto.cf" will make sure that
sendmail only listens on the loopback interface and doesn't accept
e-mails from the network.
If you desperately want the old scheme back use the instructions below:
1.) Stop the mail services:
2.) Add this line to "/etc/rc.conf" ...
... and remove this line if it is present:
3.) Remove "/etc/mail/submit.cf".
4.) Make "sendmail" setuid "root":
/usr/sbin/chown root:wheel /usr/libexec/sendmail/sendmail
/bin/chmod 4555 /usr/libexec/sendmail/sendmail
5.) Restart the mail service:
