[Plugin: Contact Form 7] pass html text inside textarea

Hi, I have this problem.

I need to pass html text inside a textareas, but, when I receive the email, the tags were trimmed! I receive only text.

I checked and unchecked “Use Html” in the option panel, but nothing happens.

How can I solve this?

Thank you.
