Hello Symantec Support,
It appears that one of our subnets has been blacklisted in your database and this is causing us problems. 46.21.145.0/24 is the subnet in question.
One of our clients uses an IP space within this network and apparently they cannot send e-mail messages to recipients using Symantec Protection Suite Enterprise, as the sender's IPs are blacklisted. If I understand correctly, this strongly relates to other similar posts in this forum, where a user applies for de-listing only to find the same IP listed in your database several hours later.
Please look into this problem, this is damaging for us. We need the reason for this listing of an entire /24 subnet. I would appreciate if you addressed the issue swiftly.
With kind regards,
Daniel Walesiuk
