Hi Maciej,
Thank you for reaching out and apologies for the delay.
I'm sorry you were having this issue.
The site is still active and the IPs are no longer listed.
Regards,
Yamma

Subject: Remove a domain from the blacklist
Hello. I am the administrator of the mail system: 212.33.71.231, 212.33.71.232 (uwb.edu.pl) and I would like to ask you to unsubscribe these two servers from the symantec blacklist. We got there because one of our e-mail accounts had been hijacked (some time ago) and it started sending out unauthorized letters. However, we quickly located which account and changed the password so that this would not happen again.
I tried through the site but this site seems to be inactive for a long time

Your blacklist is the only list that blocks our emails.
I would like to ask you to remove our two addresses as it is cumbersome to communicate with our clients.
