1) backup your current configuration, better whole /etc/mail directory

tar zxvf /root/etc_mail.tar.gz /etc/mail/

2) prepare configuration file
cd /usr/lib/sendmail-cf/cf 
cp cobalt.mc my.mc

3) edit configuration file, add dnsbl rules

pico -w my.mc
after virtusertable feature add dnsbl line: 

FEATURE(dnsbl,`dnsbl.njabl.org',`Message from $&{client_addr} rejected - 
see http://njabl.org/lookup?$&{client_addr}')

(it's your choice what to add, try searching for dnsbl on cobalt-users 
archives http://list.cobalt.com/mailman/listinfo/cobalt-users )

4) rebuild configuration

cd ..
m4 cf/my.mc > ~/my.cf

5) find defferences: 

diff ~/my.cf /etc/mail/sendmail.cf
Significant differences for me are: 

+# Pop-before-smtp secondary access hash
+Kpopauth hash -a<MATCH> /etc/mail/popip.db
+
+# Pop-before-smtp secondary access hash
+Kpopauth hash -a<MATCH> /etc/mail/popip.db
+
+# Pop-before-smtp secondary access hash
+Kpopauth hash -a<MATCH> /etc/mail/popip.db
+

( that's buggy GUI added it 3 times - no need to copy it) 

+O AliasFile=/etc/mail/aliases.majordomo

(needed for majordomo) 

-#O MaxMessageSize=1000000
+O MaxMessageSize=10485760

(10Mb message size limit) 

You have to add those lines MANUALLY to my.cf, unless you do you may 
have problems with the GUI.
Skip all changes presented by dnsbl.m4 and other rulesets.

Other way is to insert dnsbl rulesets manually into sendmail.cf - you 
may find many examples in cobalt-users archives. 

now copy my.cf to /etc/mail/sendmail.cf (BACKUP sendmail.cf to safe 
location!!!!!) 

cp ~/my.cf /etc/mail/sendmail.cf

6) restart sendmail

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

Check for errors here and in /var/log/maillog ... 


If you want me to do this for you - please contact me off-list.
