SOLVED SPF record at AWS

[zulkamalabdrahman]

Hello...i'm using cron at AWS,
we use cron server to deliver mail for update purpose
Notification Email sender is in cron server
Notification Email Receiver is in AWS server
For some reason,AWS reject an email from my cron server with the error as per below:

"550-The mail server does not recognize root@xxxxxxxxxx as a valid sender"

Why suddenly AWS recognize my cron server as a invalid sender?...we not doing any changes...With invalid spf sender...we got rejected from AWS.

Full error as per below:
The original message was received at Wed, 30 Nov 2022 10:00:52 +0800 from localhost [127.0.0.1]

----- The following addresses had permanent fatal errors ----- [email protected]
(reason: 550-Verification failed for
<[email protected]-southeast-11.compute.internal>)
(expanded from: <[email protected]-southeast-11.compute.internal>)

----- Transcript of session follows ----- ... while talking to

<[email protected]-southeast-11.compute.internal>
<<< 550-The mail server does not recognize [email protected]-southeast-11.compute.internal as a valid sender.

550 5.1.1 [email protected]... User unknown <<< 503-All RCPT commands were rejected with this error:

Hello! It appears the email from your cron server is being rejected because the root@hostname email isn't recognized as a valid email account on the cron server.

Can you try whitelisting the cron server from within WHM on the AWS server to see if this allows the emails to be received? We have an article below that contains the steps to whitelist the cron server from Sender Verify checks:

The steps from the article in my last reply would allow you to whitelist emails sent from your cron server to your AWS server. This should prevent the sender verification errors you're receiving. Let us know if you're still seeing issues after applying this change. Thanks!

@zulkamalabdrahman - if you were trying to include a file path or command the Forum can sometimes block that and cause issues with the post.
