Hi Ramesh, I had a similar problem, but not using Amazon services.
I'd suggest you to check your DKIM configuration since its little bit tricky. This is my suggestion: 1) Check your trusted-hosts file and make sure your sending server's IP is on that list 2) Check your key list and make sure your domain is listed there 3) Check your dkim-filter.conf and make sure your domain is listed in the "domain" field. I hope this can help. Good luck. -- Rafael Em 12/01/2013, às 07:50, Ramesh <itsrames...@yahoo.co.in> escreveu: > > 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
