Title: User Does Not Exist Last modified: March 17, 2017 --- # User Does Not Exist * [trlss](https://wordpress.org/support/users/trlss/) * (@trlss) * [9 years, 1 month ago](https://wordpress.org/support/topic/user-does-not-exist-2/) * Form works and sends correctly, I receive the secondary copy of the email as the person who filled it in. When switched to my email account form successfully sends and I receive both main and copy of email. However when I put my clients email address in I get the following: * “A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: * [michele@someflower.co.uk](https://wordpress.org/support/topic/user-does-not-exist-2/michele@someflower.co.uk?output_format=md) LMTP error after RCPT TO:: 550 5.1.1 User doesn’t exist: [michele@someflower.co.uk](https://wordpress.org/support/topic/user-does-not-exist-2/michele@someflower.co.uk?output_format=md)” * The email address does exist they use it everyday, the contact form is on their domains server, so why isn’t this working? I really don’t know, please help!
