XF 2.2 Error email failed, spoofing not allowed

[FoxSecrets]

I'm getting the error below when forum tries to send email.
How can user email match forum email? I didn't get that, non sense... Can someone explain what's going on? How to fix that?

Swift_TransportException: Email to zzzzzzzzz@gmail.com from contact@xxxxxxxx.com failed: Expected response code 250 but got code "550", with message "550-Your FROM address ( bounced@xxxxxxxx.com , Fox 550-<contact@xxxxxxxx.com> ) must match your authenticated email user ( 550 contact@xxxxxxxx.com ). Spoofing not allowed! " src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php:459

Anyone can help me?

When using bounce email handling, emails will be sent from your contact address with the return path set to your bounce address. Your MTA is rejecting this, saying you cannot send email with the bounce address as the return path when authenticating as the contact address. It's something to take up with your host.
