Mail

Rackspace MailGun

For test,
use sanbox domain and need to add authorized reception (reciver) and need to accept that mail, if need to get mails.

For production:
add new domain with valid custom domain and add these 2 TXT records in DNS provider.

----------------------------------------------------------------
in postfix, (/etc/postfix/main.cf)
add smtp credentials in file
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = static:postmaster@xxxxxxxx.mailgun.org:PASSWORD
relayhost = smtp.mailgun.org
smtp_sasl_auth_enable = yes

in postfix, (/etc/postfix/main.cf)

relayhost = [email-smtp.us-west-2.amazonaws.com]:25
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes
smtp_tls_security_level = encrypt
smtp_tls_note_starttls_offer = yes
smtp_tls_CAfile = /etc/ssl/certs/ca-bundle.crt

vim /etc/postfix/sasl_passwd
  [email-smtp.us-west-2.amazonaws.com]:25 SMTP_USERNAME:SMTP_PASSWORD

Note: this username and pw are not IAM secret access key and access key. you have to create credentials. (SMTP settings -> create my smtp credentials [can create multiple credentials. all working] -> then it will generate username and pw. use those on above )

How do I capture Amazon SES feedback notifications using AWS Lambda

https://www.youtube.com/watch?v=metiKh8u9rM
https://aws.amazon.com/premiumsupport/knowledge-center/lambda-sns-ses-dynamodb/

dynamodb
Table name: SESNotifications
Primary key: SESMessageId
Add sort key: SnsPublishTime

sns
create new topic-> Name: SESemailBouncesHasa

Goto SES --> verified email address --> click on the email --> Notifications --> edit configurations --> for Bounces, Complaints, Deliveries >> select:SESemailBouncesHasa --> save config

IAM role:
Name: lambda_ses_execution

Create Role --> trusted entity type, choose Lambda --> Permissions --> select AWSLambdaBasicExecutionRole --> Next --> Name:lambda_ses_execution --> done

Select created role --> Choose Add an Inline Policy (create policy) --> Service: DynamoDB --> action:PutItem (Write category)--> resources: DynamoDB table ARN --> Review -->name:lambda_ses_execution_policy --> Create policy.
ex:
------------------------IAM Policy Begins---------------------------
{
    "Version": "2012-10-17",
    "Statement": [
         {
            "Sid": "Stmt1428510662000",
            "Effect": "Allow",
            "Action": [
                "DynamoDB:PutItem"
            ],
            "Resource": [
                "arn:aws:DynamoDB:us-east-1:12345678912:table/SESNotifications"
            ]
        }
    ]
}
------------------------IAM Policy Ends--------------------------

Then attach above policy to existing role call lambda_ses_execution



Lambda
Create function --> Blueprints --> search & click:sns-message -->
Lambda function code:
--------------------------Lambda Code Begins------------------------
console.log('Loading event');
var aws = require('aws-sdk');
var ddb = new aws.DynamoDB({params: {TableName: 'SESNotifications'}});
exports.handler = function(event, context)
{
  console.log('Received event:', JSON.stringify(event, null, 2));
  var SnsPublishTime = event.Records[0].Sns.Timestamp
  var SnsTopicArn = event.Records[0].Sns.TopicArn;
  var SESMessage = event.Records[0].Sns.Message
  SESMessage = JSON.parse(SESMessage);
  var SESMessageType = SESMessage.notificationType;
  var SESMessageId = SESMessage.mail.messageId;
  var SESDestinationAddress = SESMessage.mail.destination.toString();
  var LambdaReceiveTime = new Date().toString();
  if (SESMessageType == 'Bounce')
  {
  var SESreportingMTA = SESMessage.bounce.reportingMTA;
  var SESbounceSummary = JSON.stringify(SESMessage.bounce.bouncedRecipients);
  var itemParams = {Item: {SESMessageId: {S: SESMessageId}, SnsPublishTime: {S: SnsPublishTime},
  SESreportingMTA: {S: SESreportingMTA}, SESDestinationAddress: {S: SESDestinationAddress}, SESbounceSummary: {S: SESbounceSummary},
  SESMessageType: {S: SESMessageType}}};
ddb.putItem(itemParams, function(err, data)
{
  if(err) { context.fail(err)}
  else {
           console.log(data);
           context.succeed();
      }
  });
}
else if (SESMessageType == 'Delivery')
{
  var SESsmtpResponse1 = SESMessage.delivery.smtpResponse;
  var SESreportingMTA1 = SESMessage.delivery.reportingMTA;
  var itemParamsdel = {Item: {SESMessageId: {S: SESMessageId}, SnsPublishTime: {S: SnsPublishTime}, SESsmtpResponse: {S: SESsmtpResponse1},
  SESreportingMTA: {S: SESreportingMTA1},
  SESDestinationAddress: {S: SESDestinationAddress }, SESMessageType: {S: SESMessageType}}};
  ddb.putItem(itemParamsdel, function(err, data)
{
  if(err) { context.fail(err)}
  else {
          console.log(data);
          context.succeed();
      }
  });
}
else if (SESMessageType == 'Complaint')
{
var SESComplaintFeedbackType = SESMessage.complaint.complaintFeedbackType;
var SESFeedbackId = SESMessage.complaint.feedbackId;
var itemParamscomp = {Item: {SESMessageId: {S: SESMessageId}, SnsPublishTime: {S: SnsPublishTime}, SESComplaintFeedbackType: {S: SESComplaintFeedbackType},

ddb.putItem(itemParamscomp, function(err, data)
{

  else {
          console.log(data);
          context.succeed();
      }
  });
}
};
------------------------Lambda Code Ends----------------------------
Note: editable line ------> TableName: 'SESNotifications1'

Runtime: Node.js 4.3
Name: sesnotificationscode
Role: lambda_ses_execution
Dont enable trigger yet. --> create function

open created function --> add Triggers --> SNS trigger --> SNS topic :SESemailBouncesHasa --> enable --> save
