6. (appendix) How to sniff your POP3 password

POP3 is depreciated because you can sniff your POP3 password if you have root privilege on your machine.

To sniff your POP3 password, use tcpdump. First install it. 
# apt-get install tcpdump

Run tcpdump in this way (running tcpdump requires root privilege): 
$ touch result
$ chmod 600 result
# tcpdump -w result
Replace "result" with your favorite file name.

Use fetchmail normally, and your POP3 password will be written to the file "result". The easiest (but not always correct) way to see it is to use the command "strings" in the package "binutils". 
# apt-get install binutils
$ strings result
The output of "strings" may have a line like this: 
PASS ********
This may be your POP3 password.
