    Outlook returned mail error / spam

    We've been getting "returned mail: response error" and "DNS responded with 3 (Domain Not Found)" errors in our Outlook inbox, about 20, up to 500+ per day.

    The emails have a details.txt attached, and a copy of the email, generally bank, paypal, ebay spam e-mails.

    A sample details.txt looks like this:
    Reporting-MTA: DNS; mail.enchantedboxes.com
    Arrival-Date: Wed, 20 Mar 2013 19:25:28 -0500
    Original-Recipient: RFC822; <president@bbta-au.org>
    Final-Recipient: RFC822; <president@bbta-au.org>
    Action: failed
    Last-Attempt-Date: Thu, 21 Mar 2013 12:02:16 -0500
    Our mail server is mail.enchantedboxes.com. When I look at the headers, I see more disturbing information -- is it ok to post headers on the forums? Unfortunately, I am not knowledgeable enough to decipher all this, but am worried our mail server is being used to send out spam.

    I changed all passwords for the mail server, but it does not seem to help.

    Any support would be much appreciated!

    check your machine for viruses, maybe some malware is trying to send spam blasts and you're getting the errors. Also check the mail server logs to try to pin down where these messages are coming from.
