I am working with Sendmail 8.8.7 on a Redhat 6.0 box. <br><br>The problem I am having is that email sent from Lotus Notes goes through OK, (messages are inserted into a database of comments) but messages sent from Outlook just disappear after being sent. Since our setup is behind a firewall, I would like to completely open up Sendmail. No security at all. [Relaying won't be a problem because of the firewall]<br>I have looked at the files in /etc/mail/ and looked at sendmail.cf/cw and thought I had everything disabled there, but still no messages from any workstation using Outlook. Any suggestions for checking and/or disabling ALL sendmail security will be VERY APPRECIATED!<br><br>TIA-<br>Jim
