    I am using (Ubuntu 24.04.3 LTS (Noble Numbat)) ISPConfig 3.3.0p1

    In the /var/log/rspamd/rspamd.log file i am seeing the following error message:-

    monitored; rspamd_monitored_dns_cb: DNS reply returned 'no error' for score.senderscore.xxx while 'no records with this name' was expected when querying for '1.0.0.127.score.senderscore.xxx'(likely DNS spoofing or BL internal issues)

    What is causing this error message, and, how to fix it ?

    Note: I had to blank out part of the above error message with xxx, becuase it was triggering your forum posting filter.

    Where does it say it's an error message and it's not just an info message?

    Thanks for your reply. You are correct , it is not an error message. However, in the message it says "likely DNS spoofing or BL internal issues", which is a worrying message for me as a website host.
    It seems to me that this message has been generated when the rspamd process was querying the following network location / file:-
    1.0.0.127.score.senderscore.c0m
    The above network address would seem to me to be pointing to a location on my own file system.
    Can someone be so kind to explain what is happening during this step, and, where is this file that the message is apparently referencing, and, how to I configure the configurable parts of it ?
    How can I check for the eventual DNS spoofing issue that is flagged in the above message ?
    How can I check for the eventual BL internal issues that are flagged in the above message ?

    Thanks in advance for your replies.

    The most likely reason for this message is that your server uses a public DNS resolver, and Senderscore blocked that public resolver.

    That's not the case.

    Rspamd requests a score for a sender from senderscore and the answer it received was not what the software expected.
