  • 1.  Mail delivery failed : 553

    Posted Nov 23, 2017 06:46 AM

    I am having trouble sending individual e-mails and getting the following bouce back :

        host cluster2.eu.messagelabs.com [85.158.136.51]

        SMTP error from remote mail server after end of data:

        553-SPF (Sender Policy Framework) domain authentication

        553-fail. Refer to the Troubleshooting page at

        553-http://www.symanteccloud.com/troubleshooting for more

        553 information. (#5.7.1)

     

    I have checked that the SPF and DKIM records are correct.

    The outgoing servers don't have a problem.

    The recipient e-mail address is correct

    I am trying to reply to an email (have managed to go do vis gmail but this is not a long term solution)

    I have checked that our domain is not on any Spam blacklists.

    Would it be possible for someone to look into this:

    The IP is: 185.119.175.252
