nbsmtp 1.00-4 (i386 binary) in ubuntu karmic

 This tool is used when you don't want a big MTA on your box. Reasons are maybe
 if you want to relay your mail over the one of your provider or you have a
 powerful mail server in your company which manages the queue. This means that
 nbsmtp does not manage your local mail queue, it does only send it to a hub.
 .
 The above is all it does. To use nbsmtp you will also need an account on a
 SMTP-server which allows you to relay over it.
