    Hi Everyone,

    In my 'DNS Only' server I get some emails from the server with subject "Mail delivery failed: returning message to sender" and the following header:

    Code:
    This message was created automatically by mail delivery software.
    
    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:

    ------ This is a copy of the message, including all the headers. ------

    I have searched in forum as well, but unsuccessful.
    Anyone could give me why I receive those emails?

    Thank you a lot!

    Hello,

    Your IP address is on 2 different RBL's (Realtime Blackhole Lists).

    You need to find out why and correct the issue and then get your IP address removed from those lists. Then email should start working again.

    Thank you for reply.

    But that IP is not my IP! That email was sent by "lfd" which contains a report.
    The issue is that why I do not receive that email and it is frozen.

    Hello :)

    The notification from LFD is configured to deliver to "root@dnsserver1.MYDOMAIN.com". Is that email account hosted on the local server where the alert is generated? Are you able to send to it normally? Is forwarding for the "root" account configured?

    Thank you.

    Hello! :)

    Thank you for your response.

    As far as I know, yes it is hosted on the local. Yes I am able to sent to it. No forwarding. (if you need more information, let me know please)
    The interesting thing is that the problem is not for all emails and I am able to receive some emails from lfd, such as this one:

    Code:
                                                             
    Return-path: <root@dnsserver1.xxxxxxxxxxxx.com>
    Envelope-to: webmaster@xxxxxxxxxxxx.com

    You could try creating or modifying the following file:

    Code:
    /root/.forward
    Change it to an email address that actually is created as an email account, and then create a traditional forward to the email address of your choosing.

    Thank you.
