Since then emails from my company to any email address at their company bounce back from the System Administrator with this error: Your message did not reach some or all of the intended recipients.
There are several reasons why you would get a "550 No Such User Here" error.
This error can go both ways, meaning, people sending to your server may get the error and when you send from your server to another you may get the error.
If you recently moved your domain to In Motion Hosting and you started receiving these errors, you may have a DNS nameserver or MX record problem.
The MX records point your email address to a specific server.
