Hi, >> Now we are getting blocked by Spamhaus SBLCSS with almost all of our ip >> addresses. You don't get blocked by SBLCSS but only listed. Any recipient / provider is responsible for using the list on its own.
According to the Spamhaus site, you get listed because: - Email showing indications of unsolicited nature; - Broad-spectrum aggregated views of email deliveries; - Having poor list-hygiene; - Sending out bad email due to a compromise (compromised account, webform or CMS); - Other indicators of low reputation or abuse. According to your description (sending newsletter, different customer) your IPs are predestined to get listed there if you don't take care. Have you checked each of this points? Did you contact Spamhaus support? As you name no affected IP or range or sending hostname it is difficult to give you a hint.

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.
