  • 1.  Status code: 550 5.0.350 all mail from our domain/server being rejected

    Posted Feb 13, 2018 07:36 AM

    Hi,

    It appears that most emails being sent to recipients using Symantec MessageLabs or Symantec email filtering products are being rejected. Our domain is not blacklisted, and neither is our main public ip. I've double checked on the ip checker on the Symantec website and that also comes up clean.

    Is there somebody at Symantec I can PM our ip and domain to so that this can be investigated?

    Many thanks,

    Andy

    Submit a sample of the email that's blocked to:

    investigation@review.symantec.com

    Thanks, I've submitted an exact replica of one of the emails which was blocked to the investigation address - do you have any rough idea how long I could be waiting for a reply? It seems a lot of government authorities use Symantec for their email security so we are seriously hampered in one area of our office at the moment because of this. 

    Thanks,

    Andy
