Re: [Haskell-cafe] Amazon SES email issues

30 Apr 2016


      David, thanks for the suggestion. Are there any examples on how to send an
email? I've looked through several of the Haskell email packages and have
been able to figure out their APIs easily enough, but this one seems
incredibly complex - almost seem to have to know the internals of SES to
use it effectively and the documentation / examples are scant.

I think that package is using an outdated version of the AWS Signing
algorithm.
"AWS3-HTTPS"
I think AWS is migrating most of their APIs (who have domains / services created after a certain date) to require using the V4 Signature algorithm for all API requests.
The amazonka-ses would probably work better.

Hi everyone,
I'm having issues with sending email through Amazon SES. I'm using the
*Network.Mail.Mime.SES* package. The error I get is:
*email-test-exe: SESException {seStatus = Status {statusCode = 403,
statusMessage = "Forbidden"}, seCode = "SignatureDoesNotMatch", seMessage =
"The request signature we calculated does not match the signature you
provided. Check your AWS Secret Access Key and signing method. Consult the
service documentation for details.", seRequestId =
"8ceb250a-0dd3-11e6-892c-4fb1a14d4732"}*
What's confusing is that I'm using the same SES settings in a Rails app
as well as a small Rust console program without any issues (it works from
the same machine too). The only thing I can think of is that with this
Haskell package, I haven't found where to set certain things like the port
number (587) and so maybe it's that? Here is a small sample app that
illustrates the problem. What am I missing? Thanks.
