   its very easy actually - the only trick is finding the correct host 
name(s) - you may need to poke around a few times in dns to make sure you 
have all the hosts/ip addresses. For each host that you may be forwarding to 
add 1 line to sendmail /etc/mail/access file as follows (this is 1 line - the 
mailer may wrap it). 

So if you isp gave you smtp.isp.com do a 'host' on it and make sure you cover 
all the ip addresses and the hostnames they reverse to - 1 per line.
#
# This goies in /etc/mail/access
#
AuthInfo:<ISP_MAIL_HOST or IP Address>  "U:<your isp user name>" "I:<your isp 
user name" "P:<your isp password>"  

then rebuild. Note if you haven't done so you will need to 
yum install sendmail-devel

After editing (or creating the access file) confirm you have 
FEATURE(`access_db')dnl
in your sendmail.mc 

Then 
# cd /etc/mail; make 
# service sendmail restart 

and off you go.
