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.

Sendmail and smarthost and authenticated submission on port 587
Today I came across a small and interesting thing. One of our customer have been upgrading from suse to centos, and that also changed the mailer from postfix to sendmail. I consider myself a quite skilled sendmail person but this was a new one.
The system itself is a dumb system and we should forward everyting to a smart host. But we need to do that over port 587 and authenticated.
