Hello, we are an email service provider. Our customers use our software to send newsletter. Our software and servers are configured with all best practices like SPF, DKIM, DMARC, RDNS. We have also processes implemented for processing bounces, feedbackloops, unsubscribes and DOI subscriptions.
Now we are getting blocked by Spamhaus SBLCSS with almost all of our ip addresses. The IPs are from different networks and being used by different customers of us over multiple servers and for different subscribers. The only thing they have in common is that all IPs are registered by our company. We already tried the delisting process but with no luck and no further response from Spamhaus. The delisting process ist now being blocked. With message: CSS removal denied. xxx.xxx.xxx.xxx cannot be removed at this time. Maybe someone from Spamhaus is listening to this and can contact us or somone else can give some guidance? Any help appreciated.
