This is related to the SMTP server you are trying to send email through and the email address you're trying to send from. The SMTP server isn't allowing it. You'll need to change one of the two components.

It's down to the configuration of your SMTP server, so it's controlled by your host/SMTP provider. You'd have to contact them about it.

Otherwise, you'd have to change the "default email address" in XenForo to one they would allow.
