 Hello,

 I have an nginx default vhost with the server_name setted at `_`.

 {{{
 server_name _;
 }}}

 This cause the generation of from_email to: `wordpress at _`.
 And I saw no errors catched/displayed by WordPress. I needed to debug
 manually
 `wp-includes/pluggable.php`.

 You should display why the mail cannot be send, at least in debug mode!
 And maybe you should not use `$sitename = strtolower(
 $_SERVER['SERVER_NAME'] );`, but the address of the WordPress `siteurl`.
