POP over APOP
First
There is a foolish tool that cannot send email on APOP protocol. Yes, ok. Let’s tunnel the POP over APOP.
How to use it?
This tool requires Java VM, and type at command line:
% java -jar popapop.jar [apop mail server]
Then you can APOP to your mail server on localhost:110. Ctrl+C is to quit.
