I am not able to send emails in my Windows Live Mail account

I am able to receive emails, but Windows Live Mail will not let me send emails. I keep getting this error report:

The message could not be sent because the server rejected the sender's email address. The sender's email address was *** Email address is removed for privacy ***'.

Subject 'Re: New client inquiry.'
Server Error: 550
Server Response: 550 Access denied - Invalid HELO name (See RFC2821
Server: 'mail.thedendoggiedaycare.com'
Windows Live Mail Error ID: 0x800CCC78
Protocol: SMTP
Port: 587
Secure(SSL): No

What do I need to do so that I am able to send emails again?

I think Windows Live Mail will always use the computer name as its greeting (HELO or EHLO) to the SMTP server. What is the name of your computer? To find out, type sysdm.cpl into the start search box and press Enter. Look for Full computer name.

Meanwhile, right-click on the account name in the folder pane and select Properties. On the Servers tab, ensure that My server requires authentication is selected. Click the Settings button, then select Log on using and enter your full email address and password.

Remove any unsent messages from the outbox (below the account folders in the folder pane), then compose a new test message with a unique subject and send it to yourself. Post any new error message in your reply.
