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:
Code:
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!
Thanks,
Mike
