Back in the day there was an outfit in Australia that would send you 
nasty griefing email if you had an open relay. Sendmail was JUST coming 
out with the means to prevent being an open relay, so there was a mad 
scramble to update quickly. And that was over 10 years ago. I agree, if 
you cannot comprehend email setup, best not to do it. I took a 5 day 
course in setting up sendmail and still failed the replay part of the 
final. So, I don't run a sendmail server today. <grins> Ric
