O3 Mail System.


O3 is a fast scalable email system that supports SMTP and POP 4. It is also the reference implementation for POP 4.
As soon as I finish the documentation it will be available for download.

Okay, the documentation isn't finished yet, but you can download the tarball.

There's a README in the tarball and a makefile.

Download the O3 tarball here.
