Received data: 550 5.7.1 Unable to relay

I am trying to use the H0-ECOM100 to send an email.
My customer is running Exchange2010 for their mail server.
When I use the SMTP viewer to see what is happening I get the following

Any Ideas on what I need to look for?
Thanks

I haven't used the email functionality in the ecom*
however...

SMTP 550 shows as a "relay" related error.

From reading your other posts, it looks like you tried using smtpout.secureserver.net (which is godaddy I think) and you reported success.  Now you are trying to use a smtp server inside your LAN?

My guess is that the server wants you to authenticate before it will send on your messages.  Therefore, you need to either change the client or the server.  A quick glance at Netedit makes me think that is not possible to have the ecom authenticate, I dont even see a place for a username\password.  Therefore can you configure the email server to allow non authenticated clients either globally (bad idea because of spam I think.), maybe by IP address or somehow.

if authentication is the issue, the latest version (3.7c) of NetEdit will let you configure email authentication.

Run NetEdit to find the ECOM100, right-click on the ECOM100 in the list and select Email Configuration. Click the Use Authentication selection at the bottom of the dialog and enter the userid password.

I see "Added ability to include username/password for e-mail authentication" in the release notes:
http://www.hosteng.com/SW-Products/NetEdit3%20RevHistory.htm

However I don't see anything about authentication in the email config.


I checked my partner's PC as well and 3.7c seems to be missing the entry controls for email authentication on the Email Config dialog.

hmmm ... Assuming you have h0-ecom100 firmware version 4.0.210 or later we can go at it another way.

use your favorite web browser to connect to the h0-ecom100 (enter http://<ip address of the ecom100>) as the url

click the link for Email Setup

you should see a checkbox for "Use Authentication", click that and enter the userid and password, then click the Send button to save the configuration
