   Examples migrated from Codex:

   add_filter( 'wp_mail_from', 'custom_wp_mail_from' );
   function custom_wp_mail_from( $original_email_address ) {
   	//Make sure the email is from the same domain 
   	//as your website to avoid being marked as spam.
   	return 'webmaster@mydomainname.com';
   }

   Using anonymous functions (PHP 5.3.0+) for callback:

   add_filter( 'wp_mail_from', function( $email ) {
   	return 'webmaster@mydomainname.com';
   } );

   Example of how to use this filter to update the user portion of the email address to send from.

   <?php
   /**
    * Filter the email address to send from and replace the user.
    *
    * @param string $from_email Email address to send from.
    *
    * @return string The new email address.
    */
   function wporg_replace_user_mail_from( $from_email ) {
   	// This will give us and array with the email user and the domain
   	// like this [ 'wordpress', 'example.tld' ]
   	$parts = explode( '@', $from_email );
   
   	// Add our new email user, add @ again, and append the domain
   	// This will be hello@example.tld
   	return 'hello@' . $parts[1];
   }
   
   add_filter( 'wp_mail_from', 'wporg_replace_user_mail_from' );

   Simple way to filter the email address using str_replace() function.

   <?php
   /**
    * Filter the email address using str_replace() function.
    */
   function wpdocs_custom_wp_mail_from( $original_email_address ) {
   	// The $original_email_address value is wordpress@yourdomain.tld
   	// So we just change 'wordpress@' to something else like 'noreply@' or etc
   	return str_replace( 'wordpress@', 'noreply@', $original_email_address );
   }
   add_filter( 'wp_mail_from', 'wpdocs_custom_wp_mail_from' );
