Sendmail configuration for bugzilla

[Roland Turcan]

Hello All,

I want to set up me ubuntu 8.04 server which is running bugzilla for
sending mails over sendmail.

What and where should I put settings of smtp server of my ISP and
authentication. I need to just relay all messages sent by bugzilla to
my ISP's smtp server.

PS: I already tried to change nearly everything around sendmail, but
no positive result. How can I reinstall sendmail to get back all
"default" settings which normally come from package?

Thanks in advance.
