Does Gmail kickback emails sent when using Brave?

Description of the issue:
I’m using Brave as my browser for my emails through Zoho. Today is the first time I couldn’t send emails to gmail accounts. They keep getting bounced. I know when I forward an email from my Zoho to my Quickbooks the email gets bounced. When I use Safari to do the same exact thing the message goes through.

Steps to Reproduce (add as many as necessary): 1. 2. 3.
So far I send an email to Gmails and then it gets returned with a mail delivery message

Actual Result (gifs and screenshots are welcome!):

Reproduces how often:

Relaunch
Additional Information:

Brave won’t affect your emails here, the error message would’ve occurred in Chrome and any browser. @Ali.Res
