→Testing POP3 port 110
The following is a typical successful POP3 session:
[rchan@f16 ~]$ telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
+OK Dovecot ready.
USER ops335
+OK
PASS seneca99
+OK Logged in.
LIST
+OK 2 messages:
1 750
2 796
.
QUIT
+OK Logging out.
Connection closed by foreign host.
In the above POP3 session, Four POP3 commands were used to verify that the POP3 server was running properly, they are: USER, PASS, LIST, and QUIT.
* USER: Followed by the user/owner name of the mail box
* PASS: Password associated with the user name
* LIST: Give a list of the email in the user's mail box and the size (in bytes) of each email.
* QUIT: Terminate the POP3 session.
Note that the user name and password were send in clear text to the POP3 server. In this sample session, both the POP3 server and the POP3 client (done manually using telnet) were on the same system.
