I am having a little problem in getting e-mails sent from the firewall to users inside my network. E-mail from outside the company is received by users without any problems, but if a mail message is initiated by the firewall (such as an alert) I get the following message recorded by the sendmail process on the firewall host and the e-mail doesn't reach me: 553: mail.dy4.com. config error: mail loops back to me (MX problem?) [email protected] configuration error If I add dy4.com to the /etc/mail/sendmail.cw file (as suggested as a possible fix by sendmail.org FAQ), I get the error: 550: [email protected]... Host unknown (name server dy4exsrv1: host not found) Now the host dy4exsrv1 is an internal NATted system with no DNS entry for external use. It's IP address though is in the /etc/hosts file and the nsswitch.conf file is set to do files then DNS for resolving. I know I am missing something in the configuration, but I don't know what. This problem has been going on for sometime according to the log files but I've just inherited the nightmare of maintaining the firewall and other InfoSec issues and I want to know what is going on or going wrong!
