The Understanding Spam E-mail module provides you with the instruction and computer hardware to develop your hands on skills in the below topics.
- Configuring an E-Mail Service
- Configuring a Mail Client
- Using Telnet to Spoof a Sender
The following exam objectives are covered in this lab:
- FC0-U51: 1.2 Identify common programs, applications and their purpose (Types).
- FC0-U51: 3.1 Define basic security threats (Malware).
- FC0-U51: 3.2 Given a scenario, use security best practices (Suspicious emails).
Exercise 1 - Configuring an Email Service
In this lab you will configure a mail server on LAMP and then practice sending mail via a Telnet prompt and configuring a mail client. To better understand this technology, refer to your course materials.
In Ubuntu you can use a package called postfix to implement SMTP email transfer (a Mail Transfer Agent [MTA]) and dovecot to implement POP or IMAP mailbox access (a Mail Delivery Agent [MDA]).
Exercise 2 - Configuring a Mail Client
The next step is to configure a client mail program to test that the mail service in LAMP server is working.
Exercise 3 - Using Telnet to Spoof a Sender
Running an SMTP service without authenticating connecting users or computers is not a good idea. You can easily use a Telnet session to spoof the sender's email address.
