    I get the following error when setting up the newletter smtp:
    "Mailbox unavailable. The server response was: 5.7.1 Client does not have permissions to send as this sender"
    I have specified the mail settings in the web.config and in the newletter setup. I would think this to be a MS problem but I am using the exact connection properties in my BlogEngine.Net application with no issues.
    Any idea?

    Hello Michael McGovern,

    This is a server response, given when the server does not permit you to send an e-mail from someone else name. It seems that you are in network and the server is aware of your identity, but FROM: header is different. Then this message is returned.

    Thanks for the quick reply. I understand what the message is saying, I just don't understand why I can relay from a different application hosted on the same server when that application is not "in" network nor authorized by any other means.

    I believe I found the underlying problem. When Sitefinity sends the test message it is sending as sitefinitymailsender@telerik.com (which is not authorized). I searched for this to see if I could replace it to no avail. Is it hard coded or possibly somewhere in the database?

    Hello Michael McGovern,

    You are right, and the sender e-mail is hardcoded in the current versions. We will have to change this - it's now logged. The good news is that this is the case only when you send the confirmation e-mail, which means that you can still send your newsletters. When you create a newsletter, you can define the sender's name and e-mail.

    We apologize for the inconvenience though, hopefully we will push this fix soon.

    It is good news but "...which means that you can still send your newsletters..." is not correct. The setup will not validate and therefore cannot be activated in the smtp settings. I'll try setting it up and saving it then manual activating in the DB to see if that works.

    EDIT: After editing the DB directly it works like a charm.

    Hello Michael McGovern,

    You can create newsletters and send them without the test e-mail. Just skip this step and click on Create a Newsletter button.

    Sincerely yours,
