Internal Program Version: MailTools  2.220.0.5.42.0

MailTools is a bundle: an ancient form of combining packages into one
distribution. Gladly, it can be distributed as if it is a normal
distribution as well.

*Be warned:* The code you find here is very old. It works for simple
emails, but when you start with new code then please use more sofisticated
libraries. The main reason that you still find this code on CPAN, is
because many books use it as example.
