Swiftmailer Transport for Amazon Simple Email Service

Jan 26, 2011

On the suggestions of Chris Corbyn I re-wrote my class to use direct access and the Swiftmailer byte stream interface, no cURL anymore. It's way faster, and way cooler, if I do say so myself. You can get the latest at https://github.com/jmhobbs/Swiftmailer-Transport--AWS-SES

So, today Amazon debuted Simple Email Service. The gist of it is, send mail with them instead of your own servers. Like a feature reduced SendGrid or Postmark.

Not a lot of stuff out there for it so I thought I'd jump the gun a bit and write a transport for PHP's Swiftmailer. If you have to send e-mail from your sever and from PHP, Swiftmailer is your best friend.

Never dug into Swiftmailer's guts before, but it's pretty well laid out. All you have to do for a new transport is implement the send method of the Transport interface and you are done.

I knocked mine together pretty quick, and the only code I cribbed was the HMAC code from php-aws, because AWS was rejecting the output from hash_hmac. (Which I literally just figured out while I wrote that paragraph. Works now.)

So how hard is it to use? Easy as any other transport in Swiftmailer.

setSubject("What up?")
  ->setFrom(array('you@yourdomain.com'))
  ->setTo(array('them@theirdomain.com'))
  ->setBody("

  Dude, I'm totally sending you email via AWS.

  ", 'text/html');

  $mailer->send( $message );

So, yeah, it works.

I know there is a ton of stuff I didn't implement that I need to before this could be "production" ready, but it was a very satisfying little project.
