Are any errors being produced? What if you run this from the command line e.g.:

  perl -w script.pl 'textfield1=test@test.com&textfield2=destination@t
+o.com&textfield3=&textfield4=&textfield5=BlankSubject&textarea1=MyDat
+a'
[download]

..or even try it with the debugger from the command line..

  perl -d script.pl 'textfield1=test@test.com&textfield2=destination@t
+o.com&textfield3=&textfield4=&textfield5=BlankSubject&textarea1=MyDat
+a'

I guess I am most curious to know if the file /home/test/perl.ppt exists on your local and web servers? Perhaps add:

  die( "No such file" ) if ( ! -e "/home/test/perl.ppt" );
