I have been doing some research on how to get sendmail to only accept e-
mails from valid systems. I also saw some of the past posts on LDAP and
sendmail but I don't have access to the servers nor can I put a vb script
on them to pull that information. So instead, I wrote a script to use LDAP
to pull all the valid e-mail address from the LDAP tree. So I have all the
vaild ones but can't figure out the right way to implement it.

Based on my research I image I need to populate the /etc/mail/access file
with all the e-mail addresses


To: valid at address.com OK

But how is that going to work? Should there be a deny somewhere? Any words
of wizdom would be great!

BTW, Once I have this tested I would be more then happy to release the
