Re: [Haskell-cafe] Amazon SES email issues

Hi, Just saw a note in my code about one more thing. Actually very important. The From: email address, "*sesFrom = C8.pack "de@somewhere.com mailto:de@somewhere.com"*", has to be verified at Amazon. For "sesFrom" you can't use any email address, but can in "mailFrom". Since your Ruby and Rust code are not SES-specific, maybe you can try a more general library, like Network.HaskellNet.SMTP. I'm using it for local SMTP, but haven't tried it with SES. If you'll try it and have success, let us know. br, vlatko

Hi Vlatko, Yes, I've double checked the keys. I'm using the same ones in a Rails app as well as a small Rust CLI program and they both work (on the same machine too). So it's definitely something I'm missing on the Haskell side.

I checked my package versions, and I have: mime-mail 0.4.11 mime-mail-ses 0.3.2.2 mime-types 0.1.0.6

So it looks like we're using the same versions. I'm not sure about the E2 instance. I'll have to check with my DevOps colleague at work to make sure. If it's still SES email, I would imagine that it shouldn't matter, especially since both the Ruby (ActionMailer) and Rust (lettre) email libraries I'm using are general email libraries and not SES-specific and they both work fine, but at this point, who knows? I've tried everything else without success, but the fact that you're using it ok tells me I'm probably close and just missing a small detail or so.

Kind of surprised how difficult it's been actually. I was expecting the Rust library to be the one that gave me problems. :)

Hi David,

I'm using almost exact function as you wrote below and it works without problems. Using mime-mail-ses-0.3.2.2.

However, it works on E2 instance. Don't know if that matters.

Stupid question, but have you double checked keys?

I received similar errors when keys were not correct (they were not hardcoded, but fetched).

br,

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I think that package is using an outdated version of the AWS Signing algorithm.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.
