nmh (new MH) is an electronic mail handling system. It was originally based on the package MH-6.8.3, and is intended to be a (mostly) compatible drop-in replacement for MH. Although development of nmh is ongoing, it appears to be generally stable and is in current use. But it is possible that I may break things as changes are made. nmh is currently being developed and maintained by Richard Coleman . Please send bug reports and suggestions to the nmh development mailing list at nmh-workers@math.gatech.edu.
