No matter what you place in your form to limit the field, you script
still needs to be robust against an over-length field, as the submission
is user controlled, and may possible contain any data the user wishes to
send. (Validate ALL user input).

You can always get around the "without the sender's knowledge" by having
the validation send the user a message (on the resultant page), and
possible ask for confirmation.
