# Is Subscribe2 using wp_mail() function?

 * Hello,
 * It appears that Rackspace does not support PHP mail; they only allow SMTP, preferably
   with authentication. I see other plugins that can convert settings to SMTP, but
   I want to be sure that the Subscribe2 plug-in is using wp_mail() function versus
   PHP’s mail() function.
 * Thank you!
    Mary

 * Subscribe2 does use wp_mail().
