I changed it to this and restarted sendmail, re-ran the test and still open.
To fix the OpenRelay, just edit your /etc/mail/access to have it something like that:
8<=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-C-U-T-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # Check the /usr/share/doc/sendmail/README.cf file for a description # of the format of this file. (search for access_db in that file) # The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc # package. # # by default we allow relaying from localhost... localhost.localdomain RELAY # Loopback address to enable local mails to be relayed localhost RELAY # Loopback address to enable local mails to be relayed 127.0.0.1 RELAY # Loopback address to enable local mails to be relayed 212.63.24.21 RELAY # your Public IP address 192.168.1. RELAY # Your Internal LAN address (all mails coming from these IPs will be allowed) yourdomain1.com RELAY # Your Domain number 1 yourdomain2.com RELAY # Your Domain number 2 (if you have multiple domains) 8<=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-C-U-T-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Then save your file and type this: [root@bluewall ~]# makemap hash /etc/mail/access < /etc/mail/access To generate the database from the file /etc/mail/access and everytime you make changes in the file /etc/mail/access, you need to retype this command to enable the changes...
Like this only mails that will be touched by one of these conditions will be allowed to be relayed and every other mail will be rejected
