Re: About default relay of the sendmail
The default sendmail.cf for sendmail version 8.9.x should deny relay. If not then you must be using the previous version of sendmail.cf. Try copying the new sendmail file in /usr/newconfig/etc/mail/sendmail.cf into /etc/mail/sendmail.cf and then restart sendmail and verify. It should work. The comment portion of your sendmail.cf file should display 8.9.
Once you copied this new sendmail.cf, your sendmail should deny relaying the mails. To verify -
$telnet your_system 25
...
helo your_system
...pleased to meet you
mail from:
250
rcpt to:
550
quit
...
But it is not default with 8.8 version of sendmail.
Good luck.

Re: About default relay of the sendmail
It's all in the RCPT TO: verification Ruleset. Check the lines under the comment "check_rcpt -- check SMTP "RCPT TO" " till
# anything else is
bogus
R$* $#error $@ 5.7.1 $: "550 Relaying denied"

If you are brave, and like sendmail you should get Sendmail; by Bran Costales and Eric Allman published by O'Reilly.
