I configured remote systems postfix to relay email via my connection, the

Once system is working correctly, relaying the mail via my "relayhost"
Two other system giving me an error in log file:
"External senders are prohibited to send to local recipients without
authentication"
Authentication is the same as on the first system that is working.
Though, I notice that the first system mail.log file has:
from=<[email protected]>
The two other systems (that bounce the mail) have:
from=<>
Where is the setting for "from <>"
I use command line to test the mail.
When I use:
mailto
To: [email protected]
Subject: testing i5
test
EOT
When I login as root and send this test mail; it it shows "from:
[email protected]"
Where is the "root"comes from? How to change it, control it?
