I've installed a v2.20 bugzilla under Debian.
When I create a new account or submit a request to change password,
an email will be sent. But the sender info is incorrect, such as
bugzilla-admin-daemon@ without domain name. And it shows that the email is
sent from localhost.localdomain, which is undesirable too.
How to set these parameters correctly? Any help is appreciated.

Best regards,
