Emails to messagelabs customers being blocked with 553 Message filtered

  • 1.  Emails to messagelabs customers being blocked with 553 Message filtered

    Posted Sep 21, 2017 11:39 AM
    Hello,
     
    In the last few days all of our corporate emails to certain clients are being blocked, with the same response:
     
    553 Message filtered. Refer to the Troubleshooting page at http://www.symanteccloud.com/troubleshooting for more information. (#5.7.1) 
     
    We have checked against the troubleshooting page and cannot see anything wrong. We have a suspicion that it may be due to a recent change for one of our clients where we routed the emails being sent from the platform we provide them through messagelabs. Each email sent was also being BCC'd to one of our email address for auditing purposes, and we wonder if this has flagged something up at your end? We have reversed this now.
     
    I have emailed investigation@review.symantec.com with more info, but we also thought we would try here in case we get a faster response as it's causing us a number of problems.
     
    Any help would be very much appreciated!
     
    Regards,
     
    Nathan.
