PTR record, SPF, DKIM and DMARC are also set by spammers, and sometimes even just before a spam run. It is either choosing to do amazons work or not having any work. If more and more are blocking the amazon cloud it would make their clients leave and this finally migth have them spend more on their abuse department. -----Original Message----- To: openssl-users@xxxxxxxxxxx Subject: Re: Testing On 2020-08-31 16:28, Marc Roos wrote: > Why don't you block the whole compute cloud of amazon? > ec2-3-21-30-127.us-east-2.compute.amazonaws.com Please note, that at least our company hosts a secondary MX in the EC2 cloud, with the option to direct my posts to the list through that server. However proper PTR record, SPF, DKIM and DMARC checks should all pass for such posts.
