This is actually the correct behaviour as it stands.  The CGI perl
module, as soon as the POST data exceeds $CGI::POST_MAX (and bear in
mind this includes the form fields as well as uploaded files), will stop
reading the body data from the http request immediately and doesn't
return any parameters, so "missing fields" is exactly what the program
sees as none of the 'fields' from the form are present.

Currently TFmail doesn't check that this has happened. It can be made to
throw an error by adding:

   if ( $treq->cgi()->cgi_error() =~ /413 POST/i )
   {
      die "Document too large";
   }
at around line 110 of the TFmail.pl

but that is unlikely something we will want to put in a release version
and someone will take a look at implementing it with a proper message
page.
