I am running Sendmail 8.12.10 Redhat Enterprise WS 9. I would like for the machine to accept smtp connections from specific workstations behind my firewall. In the past, this has not been a problem. I would simply add the ip address of the workstations into the etc/mail/access file and use the makemap hash command and restart sendmail. With this newer version of Sendmail and Redhat...I am unsuccessful. I have disabled the local firewall and tested sending from the localhost. I just cannot send from another pc.
I have been reading for a few hours on this but cannot seem to find the solution. Any help would be appreciated.

I should also note that I cannot telnet from another pc (from behind the firewall). It will reply to a ping. I beginning to think that it is a network issue.
