Pablo,
You will need to build the sendmail.cf file including those "Features" in
it.

Here are the steps I've used on an XTR and a Raq 550:
1. Change to the directory where the cobalt.mc file is located.
     cd /usr/lib/sendmail-cf/cf/

2. Make a backup of your cobalt.mc file
    cp cobalt.mc cobalt.mcBackup

3. Edit cobalt.mc and add the lists you want to use to the  #Features
section. I use the following for my blacklisting:
FEATURE(`dnsbl', `relays.ordb.org', `"550 - Email blocked using ORDB.org -
see <http://ORDB.org/lookup/?host="$&{client_addr}";>"')dnl
FEATURE(`dnsbl', `bl.spamcop.net', `"550 - Email blocked by SpamCop see:
http://spamcop.net/bl.shtml?"$&{client_addr}')dnl
FEATURE(`dnsbl', `list.dsbl.org', `"550 - Email blocked see:
http://dsbl.org";')dnl
FEATURE(`dnsbl', `dnsbl.njabl.org', `"550 - Email blocked due to possible
SPAM see: http://njabl.org'")dnl

*Be sure that none of these lines wrap, as this will break sendmail.

4. Save the updated cobalt.mc file

5. Create the new sendmail.cf file.
m4 ../m4/cf.m4 cobalt.mc > cobalt.cf
*Note: If you get an error when doing this, edit the cobalt.mc file and
change the line near the top from "include(`m4/cf.m4')dnl" to
"include(`../m4/cf.m4')dnl"

5. Copy the new sendmail.cf file to where it should be.
cp cobalt.cf /etc/mail/sendmail.cf

7. Restart sendmail.
/etc/rc.d/init.d/sendmail restart

You're done! Sendmail will now filter your mail according to the lines you
added to the cobalt.mc file.

*One more note: So far every sendmail patch released by Sun/Cobalt has
broken my filtering, so be prepared to rebuild the sendmail.cf file after
applying a Sun patch.

If you have questions/problems let me know.

Regards,
Chris
