[lug] linuxconf and sendmail config

[Scott Herod]

I just learned that it was possible to relay mail through
my sendmail daemon despite my telling linuxconf that there
were no valid relay hosts and clients.  This is with 
sendmail 8.9.3 which should not do relay by default.  I'm
now trying to configure sendmail using sendmail.mc and
the m4 configuration tool.  Some links that I've discovered
are:

http://ordb.org/faq/#how_to_close

http://www.sendmail.org/m4/anti-spam.html

Can someone suggest a link to a site that will test you
without blacklisting you if you fail ( like ordb.org does )?

Thanks

Scott
