 * Hello,
 * If i make changes on pluggable.php and wordpress launched updates, will I lose
   my changes? If yes, what is the best practice to make changes on pluggable.php
   without losing changes? Do I have to place it in my child theme directory?
 * Please advice.

 * what are you trying to achieve or change?
 * core files like pluggable.php should generally be left unedited; and they will
   get overwritten with any update.

 * I want to change the sender’s email from wordpress to me, I am not willing to
   use a plugin, the only way was editing pluggable.php.
    ‘wordpress@’ . $sitename;
   >> These are the lines I changed but now I have to worry about every update. 
   Any solution?

 * You can already set an email address in wordpress admin backend under “Settings”-
   > “General” -> “Email address”.

 * When users register in my site, they get an email like: [wordpress@yourdomain.com](https://wordpress.org/support/topic/pluggablephp-1/wordpress@yourdomain.com?output_format=md)
   
   The code `$from_email = 'wordpress@' . $sitename;` in pluggable.php shows the
   sender as wordpress. This line of code displays as [wordpress@yourdomain.com](https://wordpress.org/support/topic/pluggablephp-1/wordpress@yourdomain.com?output_format=md).
 * Got my point?

 * Add fhe following in functions.php file.
 * // changing from name
    function rv_mail_from_name($name) { return ‘NAME; } //
   changing email function rv_mail_from($content_type) { return ‘EMAIL@DOMAIN.COM’;}
 * add_filter(‘wp_mail_from’,’rv_mail_from’);
    add_filter(‘wp_mail_from_name’,’rv_mail_from_name’);
 * Edit: And ofcourse change the NAME and [EMAIL@DOMAIN.COM](https://wordpress.org/support/topic/pluggablephp-1/EMAIL@DOMAIN.COM?output_format=md)
   to whatever you like.

    Thanks, but
   the code has something wrong. I am using Aptana text editor and it gave me error
   in this line: `return 'EMAIL@DOMAIN.COM';`
 * I changed the name and email to mine but still the whole website is down because
   of an error.
 * I appreciate your help

 * If I am using a multisite that has two sites (one on the domain and one on the
   subdomain). Do I have to place the code in both child themes or only on the child
   on the main site?
