I'm using CentOS 7. I wanted to test my PostFix mail forwarding so I ran
[root@server /]# echo "Subject: sendmail test" | sendmail -v [email protected] Mail Delivery Status Report will be mailed to <root>.
I don't see the email received at my forwarding address and I can't figure out where the log of what happened is. I checked
[root@server /]# ls -al /var/log/maillog -rw------- 1 root root 0 Mar 6 09:48 /var/log/maillog
But that log file is empty. How do I find out where things went wrong?
