Thanks a lot for your feedback. Could you give me some on this other 
issue.

I am mailing some data to the user using the system "cat file | mail -s 
"title" me@email.com" format.
I've used the system() for this and it works fine. I am doing a "cat" 
rather than "echo" since the data can have single or double quotes. Is 
it okay to use the system command this way, with a pipe inside it ? 
Looks clumsy to me!

I looked back some old code of mine where i used "sendmail" and there I 
do:

  def pipe_output (str)
    pipeto = '/usr/sbin/sendmail -t'
    if pipeto != nil  # i was taking pipeto from a hash, so checking
      proc = IO.popen(pipeto, "w+")
      proc.puts str
      proc.close_write
      #@main.log.info(proc.gets)
    end
  end

This works fine, too.

However, since "mail -s" requires both input, as well as some command 
line parameters (title and emailid), i was not clear whether this method 
would work.

thx.
