Add-on Amazon SNS bounce processing

[Alpha1]

When you use Amazon SES for email sending, you can setup Simple Notification Service (SNS) to receive notifications for bounces, delivery, complaints. SNS also makes grey-listing visible which is important. These email bounce messages can be fetched by XenForo by IMAP. Here is such bounce message as displayed in the XF 1.5 bounce log:

{"notificationType":"Bounce","bounce":{"bounceType":"Permanent","bounceSubType":"General","bouncedRecipients":[{"emailAddress":"example@gmail.com","action":"failed","status":"5.1.1","diagnosticCode":"smtp; 550-5.1.1 The email account that you tried to reach does not exist. Please try\n550-5.1.1 double-checking the recipient's email address for typos or\n550-5.1.1 unnecessary spaces. Learn more at\n550 5.1.1 https://support.google.com/mail/?p=3DNoSuchUser q9si245377ejb.96 - gsmtp"}],"timestamp":"2019-03-06T04:47:55.765Z","feedbackId":"0102016951545745-30b5cafa-69f7-4707-a5f5-0aebbeb8ab42-000000","remoteMtaIp":"74.125.193.27","reportingMTA":"dsn; a54-124.smtp-out.eu-west-1.amazonses.com"},"mail":{"timestamp":"2019-03-06T04:47:55.000Z","source":"myimapaddress@outlook.com","sourceArn":"arn:aws:ses:eu-west-1:873655168933:identity/myimapaddress@outlook.com","sourceIp":"xxx.xxx.xxx.xxx","sendingAccountId":"873655168933","messageId":"010201695154552e-ba737bb1-a16d-45ae-b059-8152e22c2a3d-000000","destination":["example@gmail.com"]}}

But XenForo 1.5 does not recognize this format.

I would like to see an addon that scans the messages and does the following:

1. If the message contains the word 'aborted' then ignore the message. This means the provider has greylisted us.
2. If the message contains the word 'Transient' then register a soft bounce. Use the user email address to identify the account.
3. If the message contains the word 'Complaint' then ban member to prevent more complaints. Use the user email address to identify the account.
4. If the message contains the word 'Permanent' then register a hard bounce. Use the user email address to identify the account.
