LPIC-2 DNS, Web and Mail Services Practice Question
Which TWO tools can be used to send test email messages from the command line?
⚠ Common exam trap
Many exam-takers confuse tools that can manually interact with SMTP (like `netcat` or `telnet`) with tools that are designed to send properly formatted email messages, leading them to select options that require manual protocol steps rather than automated mail injection.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
sendmail
B is correct because the `sendmail` command can be used directly from the command line to inject a test email into the local MTA queue, bypassing a full MUA. It accepts a recipient address and message body via standard input, making it a reliable tool for testing mail delivery without a full mail client.
