550 You do not have sufficient privileges to send mail

[jerome1g]

When trying to test my x10host email I was able to send email from:
jerome1g@xo3.x10hosting.com to my own personal email.
However when I tried to send an email back to jerome1g@xo3.x10hosting.com
I received the following message:

Message not delivered
There was a problem delivering your message to jerome1g@xo3.x10hosting.com. See the technical details below, or try resending in a few minutes.

The response from the remote server was:

New information

This is not the name of your Inbox email address:
jerome1g@xo3.x10hosting.com
If you are sending email(s) from here don't. You won't be be able to get email back
Instead you will get the following message:
550 You do not have sufficient privileges to send mail to this address. Please authenticate and try again.
Here is what I have found:
Under Email Accounts -- This is where you create all your email accounts
I have two
1) wordpress@jerome1greene.x10host.com
2) x10host@jerome1greene.x10host.com

Anything before ________@jerome1greene.x10host.com (you create)
This is your email address
I can now sign into either of the two email accounts and send and receive email with no problems. And yes I can also reply to the email I sent from either of the email two address. "No more 550 Message"
