POP3 Server Health Checks
The Post Office Protocol - Version 3 (POP3) is intended to permit a workstation to dynami-
cally access a maildrop on a server host. The POP3 protocol is used to allow a workstation to
retrieve mail that the server is holding for it. This protocol is documented in RFC 1939.
When the user on a client host wants to enter a message into the transport system, it establishes
an SMTP connection to its relay host and sends all mail to it.
Initially, the server host starts the POP3 service by listening on TCP port 110. When a client
host wants to make use of the service, it establishes a TCP connection with the server host.
