  • 1.  IP block listed on bad senders list

    Posted May 03, 2017 06:08 AM

    I work for an ISP that has its IPs listed on the bad senders list. The problem is, no matter which IP address out of the 1024 I selected at random to check, they all came back as a positive match - even those that are currently unassigned, and therefore could not possibly have been used to send spam (unless spoofed, of course).

    Our customers are complaing that their emails to their own customers are failing, and getting messages back such as "Your IP address is on the Symantec Global Bad Senders List." 

    Our entire RIPE NCC assigned /22 block cannot all be on the list, especially when we have only assigned a quarter of that space to customers. Our block is 185.130.156.0/22.

    Can this please be investigated as this clearly isn't right?

    No response from Symantec 7 months on?

     

    We are still experienceing this issue and it is affecting our customers and our business.

     

    Whay are our IPs being listed as poor reputation? Most of these haven't even been assigned to customers and have never been used on the internet!!!
