Good possibility. This happened when I moved site hosting to GoDaddy. But I have another domain there and I use the script without issue. Could it be a setting in the php.ini file?

A simple email script will send email to email accounts outside of the host domain but not to email accounts in the domain. ie example.com/sendmail.php will send to email.account@xyz.com but not to email.account@example.com I get the following when sending to accounts with same domain name: "Warning: mail() [function.mail]: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local inG:PleskVhostsexample.com/sendmail.php on line26" The script works fine sending to any account other outside of the domain. Something in the settings I suspect. Plesk or php settings? thx for any help...
