"wordpress" in front of the "from-field"

FAQ > Mail that comes through the contact form shows “WordPress” as its sender name. How can I change this?

Hello,

I have more or less the same issue here.

Since approx 2 days, all emails coming from Contact Form are showing ‘WordPress’ as the sender AND contact form is sending from a [email protected] address.

Since this address does not exist it creates a mess in my contact/support software (Zendesk).
Zendesk receives emails from [email protected] and tries to send an automated response.
Since the address does not exist Zendesk receives a mailer daemon notification and generates a suspended ticket….

Please note this issue occured very recently, was there an update?
