The mailconf module in Linuxconf 1.24, and other versions before 1.28, on Conectiva Linux 6.0 through 8, and possibly other distributions, generates the Sendmail configuration file (sendmail.cf) in a way that configures Sendmail to run as an open mail relay, which allows remote attackers to send Spam email.

Nessus has detected that this internal SMTP server allows mail relaying.

Nessus has detected that the remote SMTP server is insufficiently protected against mail relaying. This issue allows any spammer to use your mail server to send their mail to the world, thus flooding your network bandwidth and possibly getting your mail server blacklisted.
