OJS 3.4 Email Sender Configuration Issue

I’m facing an issue with the email sender configuration in OJS 4.3. Despite configuring the SMTP settings in the config.inc.php file, emails are still being sent with the sender’s address of the registered user instead of the configured SMTP sender address. I’m seeking assistance to resolve this problem and ensure that emails are sent with the correct sender address as configured. Any guidance or solutions would be greatly appreciated. Thank you
