[Ddclient-support] Bugfix: ddclient always sends email when not running as a daemon

[Daniel T. <da...@dt...>]

Hi!

I encountered the following bug:
When ddclient isn't running in daemon mode, it always sends mail to the 
mail-failure address, even when the dns got updated successfully.


When ddclient isn't running in daemon mode, it modifies the variable 
$result like this before calling sendmail():
    $result = $result eq 'OK' ? 0 : 1;

Sendmail() then checks whether $result is equal to 'OK', and if it 
isn't, mail gets sent to the failure address...

I've attached a patch, hope you like it :)
