Good luck with AWS/Azure IP addresses. Most cloud providers have their entire IP blocks of compute services (VM, etc.) blacklisted by the majority of DNSBL and antispam actors. If the EC2 instances act as the last outgoing relay (the last IP) you will encounter email being rejected by recipient mail servers at some point. Best solution is to have your own AS number and IP ranges and your own hosting. |
