Hi All, I am 'trying' to set SMART_HOST in sendmail to point to smtp-relay.gmail.com but when looking at the /var/log/maillog its going to mx203.inbound-mx.net. [192.110.255.243], why??? my line from sendmail.mc define(`SMART_HOST', `smtp-relay.gmail.com') I did make in /etc/mail and service sendmail restart This is the only SMART_HOST in the config file. I started with the default CentOS 7.7 sendmail.mc and have not added anything else. just changed teh SMART_HOST. Why is mail relay to mx203.inbound-mx.net ????
