Summary:
Fixes T10728. Fixes T10476. SES uses third-party code with unique, creative ideas about error handling.
- Make the error handling behavior more correct, so it doesn't try to use undefined variables.
- Simplify the error handling behavior (throw exceptions sooner, remove redundant code).
- Explicitly test for `-smtp` misconfigurations. These can arise if you read the wrong column out of the table in the AWS docs, as in T10728.
- Explicitly test for SimpleXML, to catch T10476 before it does damage.
Test Plan:
- Configured SES to use a bogus SMTP endpoint.
- Faked past the SMTP check, hit sane error on the connection.
- Undid faking, hit immediate hard stop on the STMP check.
