I set up a simple contact/email form with php verification.

In a contact form I set up should I undo html special chars when the message is sent to the office so that customer messages aren't altered?

What is industry standard?

If you have a simple form, you are likely just taking in plain text, right?  There shouldn't be a need to undo special characters in a case like that, since there won't be any.

However, if what you are concerned about is a user embedding malicious code in their message, then I would go ahead and escape everything they submit using a standard function (like PHP's htmlspecialchars) to prevent execution.  Just keep in mind that you will then need to unescape it to use it in a text-only context.

How do you unescape it? And in what part of the process do you do this?

I guess before you mail it?

I'm just going to leave it. If I tweak it too much I'll have to keep my email in it longer.
