  • 1.  501 Connection rejected by policy [7.7]

    Posted Oct 23, 2017 02:17 PM

    cluster5.eu.messagelabs.com at 85.158.138.179 is refusing to talk to one of my SMTP servers at 23.239.151.125. When my server connects, cluster5 immediately responds with:

    501 Connection rejected by policy [7.7] 18806, please visit www.messagelabs.com/support for more details about this error message.

    This is instead of the initial greeting, before even HELO/EHLO has been issued.

    No spam is being sent through 23.239.151.125 and it is clean according to all RBLs that I'm aware of.

    Please investigate / unblock.

    Thank you,
    Lennart Lövstrand

    BTW, the URL in the response just redirects to https://www.symantec.com/products/endpoint-hybrid-cloud-security and is unfortuantely of no help. I think many of us would appreciate it if you could update it to something more meaningful. Thanks.

    Please post again if this does not provide the support that you need.
