Signing emails with DKIM in Node.js
问题 I'm writing a Nodejs app that needs to be able to send email. So far, I've used Postfix in conjunction with a Nodejs module called Nodemailer to send my email through Amazon SES. Postfix has been handling the DKIM signing, but now I wish to get rid of postfix and just use Nodemailer to send emails through Amazon SES. My only problem now is finding a way to sign emails within Nodejs. I've thought of running a opendkim command using "exec" in node but haven't been able to figure that out. From
