Emails sent out by contact forms should be sent from the website with a 'from' email address such as <email@example.com> (assuming your website is example.com).
WordPress should never use the customer's email address entered into the form as the 'from' address.
Since your website is sending the emails, the 'from' address should only be one you control and matches the domain of the website. The email address the site visitor enters in the contact form can be put in the Reply-To header, so when you click reply on the email it goes to them. This is related to a mail policy change DreamHost announced in April 2012. More details are also listed here:
This is an example of a smart way to send out emails from a contact form:
From: Site Visitor <firstname.lastname@example.org> Reply-To: Site Visitor <email@example.com> To: Admin <firstname.lastname@example.org> Subject: Contact Form Submission
The email addresses above assume your website is example.com and that these are addresses you've set up on the domain.

Jetpack's contact form does not have an option to easily adjust the from address for sending mail. You can manually hack the PHP code of Jetpack to adjust that, but any modifications to the code of Jetpack run the risk of being overwritten whenever Jetpack updates. Also, Jetpack's contact form shortcodes can interfere with other contact forms.
