Postfix Appends to Sender Address


CentOS 6.9
mail ver 2.6.6

I can't get a generic mapping to work correctly. Postfix seems to be appending the sender email address with this: (root). Please see attached screen shot.

It gets rejected by the server because it's deemed invalid/unsupported domain.

How do I get it to just use the email address alone. Why is it adding (root) to the end of the email address?

https://drive.google.com/file/d/1PW5...ew?usp=sharing

main.cf:
relayhost = [secure-email-813.luxsci.com]:587
smtp_use_tls = yes
smtp_sasl_auth_enable = yes
smtp_sasl_security_options =
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_tls_CAfile = /etc/ssl/certs/ca-bundle.crt
smtp_generic_maps = hash:/etc/postfix/generic

generic:
localhost email@domain.com
localhost6 email@domain.com
root email@domain.com
@SS-A.localdomain email@domain.com
localhost6.localdomain email@domain.com
@SS-A.localdomain.com email@domain.com
root@SS-A.localdomain email@domain.com
root@localhost6.localdomain6 email@domain.com

It's appending root because you are running "mail" command as root user. Therefore it will send an email as that user. That's completely fine.
As for mail getting rejected, do you have domain publicly registered ?
Is your domain allowed to relay mail through luxsci.com ? Possibly not as mail gets rejected by relay host, not google (since you emailed to gmail address).

Your screen shot is showing the contents of a log file. That doesn't really tell us what the email From actually said.
Can you show the headers of the email?

Please use [code] tags to paste code or output, for readability.

Sent mail

This sender email address does have the appropriate permissions to send from that relay server. It's working in another application on a windows server. Just postfix is having the problem.
Also, here's an image of an email sent from another server set up the same way but with different credentials. You can see that (root) was not appended to the sender address in the sixth line from the bottom. The from email address is in this format: <email.domain.com>. In the log of the problem server it is this: <email.domain.com (root)>
