[Haskell-cafe] Amazon SES email issues

[Brendan Hay]

No examples for amazonka-ses yet unfortunately. There are brief examples in
the source repository for other services:
https://github.com/brendanhay/amazonka/tree/develop/examples/src/Example
I'll add something for SES shortly.

The amazonka-* library operations and types map directly to the AWS
documentation - so you will need to a) have an understanding of the
product/service offering b) be willing to reference the relevant AWS
documentation.
Each amazonka-* library can be considered a 'low level' interface to the
related Amazon service, with a unified AuthN/AuthZ (newEnv) and
request/response (send) interface available in the main 'amazonka' library.

For your example above, as the older AWS APIs tend to have fairly unhelpful
error messages - your only option unfortunately is trial and error. The
keys are naturally the first thing to check, make sure you haven't mixed up
the access and secret keys by accident and that they are in fact the same
keys being used by your equivalent Rust program.

Just for clarification - you mentioned port 587, are you attempting to
communicate with a non-standard endpoint?
