Mailbox unavailable or not local error messages – Plesk

If you receive this error when adding a domain:

Unable to send notification: mail() failed: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local

then you need to add a valid mailbox to your Plesk admin setup. To resolve this issue log into Plesk and click on:

Edit (under personal information)
Replace the email address with a valid, working address.

Keep in mind this error shouldn’t prohibit you from creating a site, it is just notifying you that the “site created” email will not be sent.
