The Amazon Simple Email Service (AWS SES) rewrites the Message-ID header of outgoing emails. That means subsequent failure/success notifications will not be in the same thread, because they reference a non-existing message id in the In-Reply-To header.
The rewritten message id is returned as last message of the SMTP transaction, e.g.
250 Ok <00000123456abcde-1234abcd-abcd-1234-1234-1234abcd1234-000000@eu-west-1.amazonses.com>
http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-response-codes.html
I have written a proof-of-concept patch that updates the rewritten message id in case AWS SES is used for sending mails.
Would you be willing to accept such a patch? It is kind of ugly to include provider-specific code like this, but it has no downside for people not using AWS SES and can probably be encapsulated so that it doesn't get in the way.
[JENKINS-30854] Support AWS SES Message IDs for In-Reply-To header
I looked at your changes and I think you could do it via a pre-send script instead of changing the plugin itself. See https://wiki.jenkins-ci.org/display/JENKINS/Email-ext+Recipes#Email-extRecipes-PresendScripts for some examples of pre-send scripts. You have access to the msg object.

However, I don't see how this can be done via a pre-send script: The Message-ID is only known after the email is sent, and can only be obtained by the SMTPTransport object.

Log:
Add post-send script feature
For some tasks pre-send scripts are not sufficient, like rewriting the
Message-ID based on the SMTP response for later In-Reply-To headers.
This is needed when using Amazon Simple Email Service (AWS SES) for
sending emails.
Other possible use cases are scripts that act upon failed sending
attempts.
Here is a example post-send script that does the message id rewriting
for AWS SES:
```groovy
import com.sun.mail.smtp.SMTPTransport;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import hudson.plugins.emailext.ExtendedEmailPublisherDescriptor;
String smtpHost = props.getProperty("mail.smtp.host", "");
String awsRegex = "^email-smtp\\.([a-z0-9-]+)\\.amazonaws\\.com\$";
Pattern p = Pattern.compile(awsRegex);
Matcher m = p.matcher(smtpHost);
if (m.matches()) {
String region = m.group(1);
if (transport instanceof SMTPTransport) {
String response = ((SMTPTransport)transport).getLastServerResponse();
String[] parts = response.trim().split(" +");
if (parts.length == 3 && parts[0].equals("250") && parts[1].equals("Ok"))
}
}
```
