-# Fake POP3 server
-# By Marcus Bointon <phpmailer@synchromedia.co.uk>
-# Based on code by 'Frater' found at http://www.linuxquestions.org/questions/programming-9/fake-pop3-server-to-capture-pop3-passwords-933733
-# Does not actually serve any mail, but supports commands sufficient to test POP-before SMTP
-# Can be run directly from a shell like this:
-# mkfifo fifo; nc -l 1100 <fifo |./fakepopserver.sh >fifo; rm fifo
-# It will accept any user name and will return a positive response for the password 'test'
