If you 'ping' the hostname does it return the internal address? If so, and you are using sendmail, sendmail may be looking for the MX record from a DNS lookup for the mail domain, not a generic A record. I believe that HOSTS files are only good as a substitute for A records, although I'm not sure about that. Possible fixes? Well, address to the IP if that is possible (for instance if it is an automated message from a script etc.) or simply use a different machine as the SMTP server instead of invoking sendmail locally.... Hope this helps... I'm not sure if I have a full idea of what you are trying to accomplish, but hopefully this is a start. james -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
