GPLW3Mail is a splinter project based upon W3Mail. It aims to produce a free version of the W3Mail web-mail client.
The software itself is a module-intensive perl application providing web access to POP3 servers. It will be of interest in such contexts as ISPs providing mail service to their customers, virtual-POP environments and similar.
Our current project goal is to match our branch-point from W3Mail in features and stability, after our current period of reorganization. The W3Mail codebase is very poorly written and has many potential security problems -- these issues will need to be thoroughly addressed before a GPLW3Mail release.
Aside from the code, there is no releationship between GPLW3Mail and the original W3Mail author's code. The author of W3Mail switched to a non-free licence scheme with his 1.0 release; GPLW3Mail branches from the last version of W3Mail released under the GPL.
Project contributors are welcome. At present testing is not needed; GPLW3Mail is guaranteed unstable and extensively broken, and no further exploration of that aspect is currently required. :)
