Hi,
we are a hosting company with a sinlgle IP class.
It is 213.238.169.0/24
The whole class seems to be listed by symantec **** however we are checking our outgoing email very strictly and there is no outgoing spam. We need to learn why symantec is blocking our emails without clarifying the reason. Outgoing emails are blocked only on receivers where there is a symantec security product. The connection gets timed out and what we are told from receivers is that our IP is in Symantec global list. When we query our Ip class (213.238.169.0/24) from https://ipremoval.sms.symantec.com/ all the class is blacklisted however we dont have an outgoing spam issue. Even our passive IP addresses which are not being used are in **** which does not make sence.
Please find the error log in the attached document, the receiver is a Bank in our country which uses symantec products.
I already asked the same question under email security community however I was told that messaging gateway is the right place to open the thread.

How can we get information on this matter?
Kind regards.
