Maybe it's a good idea to put a couple of common sendmail and possibly 
others MTA config files on a web page, it don't really care who's website. I'm
gonna put my sendmail config file (with Anti Spam stuff, see other thread)
on my site. There are a couple of others who also have config files on their
site eg. ww.hopf.demon.co.uk. But i figure it would be nice to have a
collection of config files which are commonnly used on a central site. So when
new/other user's ask about setting up mail for use with demon we can just point
them to that central site.

If there already is such a site i'd like to know.

Cheers.
