Your own MTA (Postfix) has accepted test message and put it in mail queue. So,
notifications are working.

It seems like you mixed up client and server ports. I don't think you should
use submission port to send notifications - gmail requires authentication for
MUAs.
I'm afraid, you can't get your own mail server up and running if you don't know
how SMTP works.
