Drupal get site wide email address?

Question

In my module I want to get the site wide email address - the one that is set in the site information admin pages and that is used for all automatically send email messages.

How can I do this?

Answer 1

$site_email = variable_get('site_mail', '');

Answer 2

Looking into the system module, I found the settings form references the following:

variable_get('site_mail', ini_get('sendmail_from')
