sorry I wasn't clear

If the email is being sent to some addresses, but not others, the SMTP server is refusing to relay to those addresses for some reason. contact the host and see if they can can look into the SMTP server error logs, there are likely some clues into why the SMTP server is not relaying to those addresses in the errors logs. 
Sorry I wasn't clear in my problem. The Powerstore only ever emails the "Forget Password" information. It will do that every time. But, the Powerstore doesn't ever email the registration information or the order information.
It is not because the SMTP server is refusing to relay to an address because it does email the "Forget Password" information. It does not email the registration information (to the same email address) or the order information. I have checked all the spam filters.
