This is a very simple text based mail checker. It is not designed for pop3 mailbox checking–just use fetchmail to d/l it all, then check it locally. It includes a small tool kit to help write your own dockapps.
For comments, see the original dockapps.org entry.
A newer version may be available in the Window Maker dockapps git repository:
git clone https://repo.or.cz/dockapps.git
