Hi,
I am writing as an e-mail system adminsitrator of Istanbul Technical University in Turkey.
Our SMTP gateways blacklisted by Symantec Global Bad Sender Database.
We are one of the big university in our country, we have thousands users, including student, academicians and officers. So the communication driven on e-mail system involves not just personal aspect but also involves the corporate side with other universities and companies.
Since Symantec provides very qualified and trustful security platforms, many company and corporation protects their e-mail infrastructure by your products. However our smtp gateways get caught by your blacklist, this makes impossible the corporate communication of us through domains that uses Symantec products.
So I kindly request that please mark our domain and IPs as a good sender. We have effort to cut the malicious and unsolicited email transactions. And also we have valid SPF and DKIM record in DNS tree.
Domain: itu.edu.tr
SMTP Server: 160.75.25.118
SMTP Server: 160.75.25.119
