8. SMTP Port 25 - SMTP relay between two email servers.
- Unsecure and vulnerable to attacks
9. SMTP Port 587 - Default port for mail submission and is used for Secure Sockets Layer (SSL
)/Transport Layer Security (TLS).
-In the handshake process between a client and the server, the client will try to
upgrade to an encrypted connection.
- If the server is compatible, that is, supports SSL/TLS, a secured TLS connection
will be established.

CORRECT Answers
- If the server is not compatible, a connection will still be established but for a
plain-text transmission.
10. SMTP Port 465 - Alternative port for mail submission and is used for implicit SSL/TLS.
- In the handshake process between a client and the server, a client will try to
upgrade to an encrypted connection but will not check for server compatibility.
- If the server supports SSL/TLS, the connection will be established and is secure.
If the server is not compatible, the connection will be dropped, and transmission
will not occur.
