Who Should Attend:
System and network administrators who are responsible for sendmail security, particularly on firewalls and other similar systems. This is a fast-paced tutorial for those who are already familiar with configuring and administering sendmail.

sendmail is a powerful Mail Transport Agent that can be configured for many different environments, from firewalls to workstation mail servers. These environments have different security requirements; in particular, in a pure relay configuration (with no local user accounts or delivery) sendmail can be configured to give up root permissions.

Course Outline:

• Principles of sendmail security
• How to configure sendmail on systems that have special security requirements, notably firewalls and proxies
• Configuring sendmail to run as a non-root user
• Running sendmail in a "chroot"ed jail
• How to (and when to) relax sendmail's file security checks
