  • 1.  501 Connection rejected by policy

    Posted Dec 02, 2016 03:14 AM

    Hello,

    I have an email system on IP: 104.243.65.51

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

    The server is not black listed, implements DKIM, SPF, DMARC and on http://ipremoval.sms.symantec.com/lookup/ it reports: The IP address you submitted, 104.243.65.51, does not have a negative reputation and therefore cannot be submitted for investigation.

    Could you please check why this address is getting blocked?

    Thanks Michel

    Hi Michel,

    I have found that your IP is listed on our internal Blacklist. I have raised an internal case to get this removed and I will let you know as soon as it is resolved.
