Hi All,
We have ec2 instance in Amazon web service. i've configured local postifix to use external relay server, DNS records created using Amazon Route 53 and created SPF & DKIM, everything works fine when sent mail through webmail (configured in relay server). When mail sent from ec2 instance it will not add SPF or DKIM Received-SPF: none (domain of turbo.localdomain does not designate permitted sender hosts) Please help me to resolve this issue. Thanks Ramesh
