Sender email through theme function.php

Hello,

Until WordPress 5.7 update I was able to put the following snippet into my theme function.php to send the site emails through a different email address due to the strict filtering we have on our network.

/*--------------------------------------------------------------
	// Sender email address
--------------------------------------------------------------*/
function wpb_sender_email( $original_email_address ) {
		return '[email protected]';
}
// Function to change sender name
function wpb_sender_name( $original_email_from ) {
		return 'My Company';
}
// Hooking up our functions to WordPress filters
add_filter( 'wp_mail_from', 'wpb_sender_email' );
add_filter( 'wp_mail_from_name', 'wpb_sender_name' );

But since WordPress 5.7 update if anyone tries to use the password reset on the login page they get the following error:

“Error: the email could not be sent. Your site may not be correctly configured to send emails.” message when they try to change their passwords.

When I remove the code from function.php the error message disappears but the email gets filtered on our network.

Can anyone think of a way I can get this to work?

Many thanks
