I am building a e-mailing app and I am using Amazon SES API to send emails and long with that I am adding the DKIM signature to the email which are being sent. Presently the app is in the testing mode. I am able to send email but one thing I observed in the sent email is that the DKIM sign says dkim="hardfail" which is not a good thing.
How do I configure the setting. I am running ubuntu 10.10 EC2 instance in production and ubuntu 11.10 locally. I have used this GEM https://github.com/jhawthorn/dkim to add DKIM Sign.
Its been already 2 days I am try to solve this issue, kindly help me out.
