Answers

1.

False. You have no idea how secure the networks are between your computer and the other end of the connection. There may even be a wireless link at the other end that you don't know about. SSL will encrypt your session from end to end.

2.

A certificate authority, or CA, is a trusted organization that digitally signs a certificate and guarantees through a number of checks that the person or organization using that certificate is genuine.

3.

Certificates can be used in mail to digitally sign and/or encrypt a message. Certificates are also a necessary component for SSL encryption between the mail client and server.

4.

Mac OS X: Keychain Access; Mac OS X Server: Server Admin

5.

An open relay is an email SMTP server that permits anyone on the Internet to route messages anonymously through it. These are often abused by spammers.

6.

Spam is detected with Spam Assassin. Viruses are detected with ClamAV.
