2 of our customers still have Cyberoam appliances in use because the modules are still valid until the end of the year and they are currently not willing to switch to a Sophos.
If i check the domains, they have no entry in any RBL-Check (Spamhaus...) and the certificates of the mail servers are valid.
The mails are accepted by every firewall except Sophos appliances. After consulting the IT departments of the respective companies, the mail is rejected by the RBL check because there would be an entry at: fur.global.sophosxl.com.
How the hell can I remove my customers domains there?
