This is pretty much dead, and I'm only keeping it here for anyone crazy enough to still want it.
It's an alpha alpha alpha alpha version of m4mailconf, a module for linuxconf to generate sendmail.mc files. In time I should have an actual working module. For now, be VERY VERY CAREFUL. If you break your mail setup with this, it's not my fault - this module does not replace your sendmail.cf.
The module is available in SRPM and tar.gz formats.
Build instructions are in the README file, along with caveats and notes on what works and what doesn't.
