Using POP Commands in a Telnet SessionThis section outlines some basic POP commands that you can use to verifythe connection and condition of your mail box on the POP server. Beforebeginning sending commands with Telnet, you may want to define a log fileto capture the text of the session. To capture a Telnet log, follow thesesteps:
- On the Terminal menu, click Start Logging.
- In Open Log File, type a file name for the current log. Note the folder location of the file. The default location is the Windows folder.
