puts "Content-Type: text/plain"
puts

subj = ENV['PATH_INFO'] || ""
subj.gsub!("'", '"')
msg = STDIN.read || ""

# system "env"
# puts subj
# puts
# puts msg

f = open("|mail -s '#{subj}' [email protected] 2>&1", 'r+')
f.write msg

f.write "\n\n"
f.write "Sender IP is #{ENV['REMOTE_ADDR']}\n"
# f.write ENV.to_hash.map{|k,v| "%-15s %s" % [k,v]}.join("\n")
# f.puts
# f.puts "."   # wtf why does this stop an error
f.close_write
out = f.read
f.close

# puts "Seems to have sent."
