So what's a 5.1.1 code anyway?

So I sent an email to eagreements@msdirectservices.com as I didn't get an Acceptance email and my SBS/Office SA expire tomorrow and the new one kicks in and I don't see the acceptance email to place the new SA into the MVLS web site to get the active SA'd agreement up there.

So I send it... and the email bounces back...

Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
eAgreements@microsoft.com:
205.248.106.30 does not like recipient.
Remote host said: 550 5.1.1 User unknown
Giving up on 205.248.106.30.
Okay so I don't think that's a spam bounce.... hmmmm

Delivery status notifications in Exchange Server and in Small Business Server:
http://support.microsoft.com/default.aspx/kb/284204

Numeric Code: 5.1.1

Possible Cause:

• The e-mail account does not exist at the organization the message was sent to. This issue may occur if there was a problem when users were moved between sites. For example, if a former Administrative_Group_1 user moves to Administrative_Group_2 and then replies to an old e-mail message, or if the user does not re-create his or her Outlook profile, an old Administrative Group style LegDN address will be used, and an NDR is generated.
• The message was sent to obsolete personal address book entries.
•

The categorizer rejected delivery because you configured your SMTP contact with see comment SMTP RFC821 characters

Looks like mvlshelpa@msdirectservices.com works ...but not eagreement... weird...

P.S.  I tried msdirectservices and microsoft ...no go..

I've often had MS Support services attempt to send e-mail to me using nonvalid from addresses (sender@contoso.internal ) and I had to have one redirect it to my google account (Which accepted it fine)
