192.168.69.0/24 should be the proper setting here. 192.168.69.19/30 is not a 
proper network. Are you absolutely sure that you did every step in the howto?

I used mail to send a test message and it worked fine ( after I read the man 
page -- I haven't used mail to send a message for 20 years or more!).

There must be other errors in your postfix config.

When you start postfix, does it throw any errors in the logs?
