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: 0 -

Already add our cron server ip to the setting as per images. Hopefully can settle the issue. Will update again tomorrow. Thanks support team... 0 -
Hi, [QUOTE]May i know what is the meaning of "whitelisting the cron server from within WHM on the AWS server" Could you please decribe more?Please advice...
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!0 -

@zulkamalabdrahman - if you were trying to include a file path or command the Forum can sometimes block that and cause issues with the post. 0
