    Hi,

    My Open Exchange server are flaggings the emails as SPAM.  The root cause appeared to be in the received header as high lighted in red.  Is there a setting or configuration that I need to set in form?

    Best regards,

    Michael

    Here is my source:

    Spam detection software, running on the system "spam1.pem.inap.sea.dotster.net", has
    identified this incoming email as possible spam.  The original message
    has been attached to this so you can view it (if it isn't spam) or label
    similar future email.  If you have any questions, see
    the administrator of that system for details.

    The original message was not completely plain text, and may be unsafe to
    open with some email clients; in particular, it may contain a virus,
    or confirm that your address can receive spam.  If you wish to view
    it, it may be safer to save it to a file and open it with an editor.

    I think you can most of the hight point issues by:

    a. Changing your "Reply to" address from your yahoo address to default JotForm

    1. Click on "Setup and Share" tab,
    2. Click on "Email Alerts",
    3. Select "Notification",
    4. Click on "Reply-to and Recipient Settings",
    5. Change "Sender Address" at the top to default JotForm email address.

    b. Converting your emails to plain text

    1. Click on "Setup and Share" tab,
    2. Click on "Email Alerts",
    3. Select "Notification",
    4. Click on "Convert to Plain Text",
