[Plugin: Contact Form 7] sender is always ‘wordpress’

I have specified the email in the contact form as follows:
[email* email]

I then call this field in the email as:

[email]

Nothing special so far.

In addition, I’ve placed [email] in the ‘From’ field so i can quickly respond to the sender using the ‘Reply’ button in my email client.

This works fine, but the Sender (eg. [email protected]) is displayed in all email clients as:

WordPress <[email protected]>

I’d prefer it was simply:

[email protected]

Anyone have thoughts on how I can remove the ‘WordPress’ prefix?
