I have set up a rule set for inbound emails in AWS SES. This inbound rule receives an email and a lambda function processes the email content.
This worked up until a couple of days ago when I started receiving the error message below when sending emails to the address connected to the inbound rule:
4.3.0 smtp; 451 4.3.0 This message could not be delivered due to a recipient error. Please try again later
However - the rule still triggers the corresponding lambda function which means that the email is actually delivered.
How can I prevent the server from sending this response?
Under Actions in Email receiving add a Stop rule set action where it should stop checking additional rules.
The lambda function that I thought was causing this was not the culprit in this case.
There was another rule in place which failed since it did not have access to the S3 bucket in which is was supposed to save incoming emails.
Lesson learned: This error message is sent back from the email server when an incoming SES rule fails to exit successfully.
If anybody comes across this in future and Karl's solution isn't the issue: I had this exact issue and it turned out the action ordering was causing the error.
If the Lambda function action was before the S3 action, it threw the 4.3.0 smtp; 451 4.3.0 This message could not be delivered due to a recipient error. Please try again later error, even though the flow worked as expected. If you swap them over so it is S3 then lambda, it works fine.

Prerequisites
I use AWS SES to send an email with event publishing to track the delivery status.
Problem
I'm looking for an event to make sure that an email is successfully sent to the end-user.
Description
Following AWS documentation, this type is suitable:
Deliveries – Amazon SES successfully delivered the email to the
recipient's mail server.
However, this event I get also in case Hard bounces.
For example, email status flow is:
Sends -> Deliveries - in case of successfull delivery
Sends -> Deliveries -> Hard bounces - in case I provide invalid recipient name, e.g. invalid#domain.com or 1234567890#domain.com
I don't expect Hard bounces after Deliveries.
If this behavior is correct then I need some additional event for sure success.
Something like this is expected in case of successfull delivery:
Sends -> Deliveries -> Success
I know that there are other "success" events like Opens, Clicks, Subscriptions, but they require additional action from the end-user.
Implementation details
I use Verified identity as an email sender.
A configuration set is used to redirect status events to SNS.
Finally, SQS is subscribed to this SNS to have all events in one place.
I tried several ways to send an email:
Java code using AWS SES SDK
Sending simulator with predefined and custom recipient's
The result is the same (as described above)
I think it is impossible to have a Success status because AWS cannot guarantee when the recipient mail server will reply with a Hard Bounce. You yourself have to define how long to you want to wait until you consider a delivery as successful. For example, if no hard bounce after 5 minutes, then it is a success.
If your use case is for analytics, I will simply capture more event types (for example log both Deliveries and Hard Bounces), and then count my success as Count of Deliveries - Count of Hard Bounces.
If your use case is for event-driven workloads, we need to define first what is considered a Success. For example, if we define Success as no Hard Bounce after 5 minutes, we can configure a Lambda function to trigger 5 minutes after a Delivery event. In the function, check if a subsequent Bounce event occurred. If not, the delivery is considered successful and then you can proceed to do what you want to do.
This is what I got from aws support about delivery status of an email.
Amazon SES will continue making several delivery attempts until
receiving a successful response from the recipient mail server, or
until 840 minutes elapse. If Amazon SES is still unable to deliver
the email/message during this period, it stops sending the email and
will then return a bounce message/notification.
According to this you can't be sure about the bounce or any other status within 5 minutes.
AWS does not have visibility to confirm if the Recipient Mail Server was able to deliver the message to the recipient email address when you get a 250 OK(it's confirmation that aws has delivered the message to recipient's mail server).
So there is no way you can be sure.
I can't seem to find much information on this one. I have a requirement to include the error message body in the email alert that is sent out when the GCP alert policy is triggered.
Now I can see from the documentation page that certain variables can be added relating to the policy itself but does anyone know of any easy way to parse the log contents failure payload and pass it? This may be a failure of understanding on my part.
What I have tried is to setup a cloud function that raises an error with a specific message whenever the http request is made. I have setup a policy on the logs for this function that trigger for the error severity. This works fine but what I can't do is parse the error message in the email alert body. Does anyone know of a good work around for this or am I missing something?
I'm getting bounce when I send an email to a specific address using SES, from gmail the mail is delivered correctly
For Transient -> General AWS says The recipient's email provider sent a general bounce message. You might be able to send a message to the same recipient in the future if the issue that caused the message to bounce is resolved.
How can I fix the issue if I do not know the problem?
"eventType":"Bounce",
"bounce":{
"bounceType":"Transient",
"bounceSubType":"General",
"bouncedRecipients":[
{
"emailAddress":"{some_email}",
"action":"failed",
"status":"5.7.8",
"diagnosticCode":"smtp; 535 5.7.8 Error: blocked by Block Address check from 54.240.8.90"
}
],
"timestamp":"2019-07-03T19:48:56.445Z",
"feedbackId":"0100016bb962013a-6cd68815-3c51-4216-9946-50f01b923057-000000",
"reportingMTA":"dsn; a8-90.smtp-out.amazonses.com"
}
Not much you can do, seems like the recipient side is checking IP reputation and found that SES IP (sending IP) 54.240.8.90 is in the blacklist, it also sent you a bounce back with custom message "smtp; 535 5.7.8 Error: blocked by Block Address check from 54.240.8.90".
Seems like they're using SORBS SPAM .

Couple of things you can try:
Remove the IP from SORBS by yourself (it may get added again)
Contact AWS to contact them to remove it from Blacklist.
Try dedicated IP pool.
I don't have a ton of experience with Amazon SES. For a client of mine, I maintain a small subscription list (about 1300 people) and I use Amazon SES to send messages through from the WordPress blog that this group is subscribed to, whenever there is a new post. Every so often I get complaint notifications from Amazon, but there is no identifying info to tell me who the complaint is from so that I can remove them from my list. How can I use those emails (or some other part of SES) to effectively remove these recipients? I have no intention of sending to anyone who doesn't want to receive these emails (even if they have not unsubscribed on the blog directly), but I can find no way of addressing these complaints.
The messages contain (in addition to the content of the email), information like the following:
User-Agent: ReturnPathFBL/1.0
Abuse-Type: complaint
Arrival-Date: Thu, 17 Aug 2017 10:22:08 +0000
Feedback-Type: abuse

UPDATE
This is maddening. I have now setup an endpoint on my server, and when subscribed to SNS topic I correctly receive logs that I have been subscribed. But then...NOTHING. I still get the useless emails, but I get zero SNS notifications, despite being verified. Still investigating.
UPDATE II
Success!! It turns out that setting up SNS (or email notifications) on the DOMAIN was meaningless. I had to set it up specifically on the EMAIL SENDING ADDRESS. This was CRUCIAL but not at all obvious (at least to me)
Your question been addressed in amazon blog.

Make sure you are following the procedure to handle bounces and complaints from amazon aws.
I am having a strange problem with my SMS Gateway. The SMPP connection to the external gateway is fine, and outgoing messages are never a problem.
The problem is to do with my incoming.cfc - the gateway instance points to "incoming.cfc" and that file is set up to send an auto reply to the incoming message and add some details to a database. Simple and it works as tested.
Every couple of days though the incoming messages stop getting added to the database, and the auto reply messages don't get generated. The log files indicate that (although no changes have been made to either the incoming.cfc file or any other files or configuration settings) we have somehow "switched back" to an earlier version of the incoming.cfc file - I can tell this because the wording of the return message in the logs matches this earlier version.
I have read Adobe documentation that says the gateway will use whatever incoming.cfc it is pointed to and you don't need to refresh the event gateway instance if you change the cfc - even though the old cfc has been deleted off the server entirely and the new one not changed - when the problem occurs (every other day) an instance refresh appears to fix it.
Has anyone seen anything like this?
Thanks for listening!
Simon
Try renaming your cfc from incoming.cfc to incoming2.cfc
