I had to get sendmail working on my ubuntu / well kubuntu installation today – well i actually didn’t need to configure that, but i hade to test some programs that should use smtp to forward mail to an external mailserver. And i ran this in wmvare. And then i found out that i never had configure that. Next part was that by default, ubuntu and kubuntu is using exim as the mailer, not the real sendmail system. So I thought that I should get it to work. Kind of out of the box.
