  • 1.  501 Connection rejected by policy [7.7]

    Hello,

    I have an email system on IP: 188.165.166.129

    My users and I have been getting some mails returning with: "501 Connection rejected by policy [7.7]"

    The server is not black listed, implements DKIM, and on http://ipremoval.sms.symantec.com/lookup/ it reports:

    "The IP address you submitted, 188.165.166.129, does not have a negative reputation and therefore cannot be submitted for investigation."

    Could you please check why this address is getting blocked?

    Thanks,

    Hi Luca.

    I have now reset the confidence of your IP accross our network and also removed your IP from our internal blacklist. This has fixed and resolved your issue of sending emails to our customers.

    Kind regards
