POP3 is an application-layer Internet standard protocol used by email clients to retrieve email from a mail server.

POP3 Port

• IPv4 Ports: POP3 port for IP version 4.
• IPv4 Secure Ports: Implicit port for IP version 4.
• IPv6 Ports:POP3 port for IP version 6.
• IPv6 Secure Ports: Implicit port for IP version 6.

Service Time

Mode:To apply service time for POP3 response.

1. No Service Time: No service time delay is applied. Helps in doing max load testing.
   • value1: Not Applicable.
   • value2: Not Applicable
   • Description: Helps in doing max load testing
2. Exponential Random: Exponential random service time with median of specified seconds is applied. For exponential random distribution, median is roughly around 1/4th of the mean. This takes a random value equivalent to median time.
   • value1: Median Time(> 0)
   • value2: Not Applicable
   • Description: This takes a random value equivalent to median time.
3. Constant: A constant service time of specified seconds. Helps in doing controlled tests.
   • value1: Constant Time (> 0)
   • value2: Not Applicable
   • Description:Helps in doing controlled tests. It takes a constant value. As one can calculate the number of page requests expected within certain duration.
4. Uniform Distribution: It is more Realistic. The value is a random value between the minimum and maximum time defined. Min should be less than or equal to Max.
   • value1: Minimum Time (>= 0)
   • value2: Maximum Time(> 0 and >= Min)
   • Description: It is more Realistic. The value is a random value between the minimum and maximum time defined. Min should be less than or equal to Max.

Command:

• GREETING: Used for session initiation.
• USER: Username.
• PASS:Password.
• STAT: Displays the number of messages currently in the mailbox and the size in bytes.
• LIST: To get a summary of messages.
• RETR: To retrieve a particular message.
• DELE: To delete a message.
• NOOP: Used as a periodic poll for new messages or message status updates during a period of inactivity
• RSET: To reset the session to its initial state.
• QUIT: To end the POP3 conversation.
• ALL: To apply service time for all of the commands, choose ALL.
• Average Time: The Time taken in between Min and Max time (Formula: (Min+Max)/2) or (no of transactions * time of each transaction / total no of transactions).
• Maximum Time: Time taken for completing the Service test.
