I am using Linode and have built a LAMP stack. I setup Google Apps (free edition) to handle all incoming mail. I've also setup Google Apps to use DKIM authentication. The problem is when my application sends mail (sign up verification, lost password, etc.) the email is not signed.
Hello there guys.
First of all, we are ESP sending emails for our customers. We want to sign the outgoing emails with both DomainKeys and DKIM. (both). I know the DKIM is successor to DomainKeys, but the Yahoo mail server still checks both of them.
