It would be awesome if this library did DKIM signing for you.
I've looked into this before and decided against this since it would require a major overhaul of the library. Amazon SES allows you to compose messages using their proprietary API or by sending a RAW email (just like your email client would send them). Currently, this library uses Amazon's proprietary way of doing things.
DKIM support for their own API is high on their priority list and will be integrated with the library when it becomes available. I'll put this issue on hold for now. Thanks for your input!
You can now sign your emails using Amazon SES' Easy DKIM feature!
