SES:535 Authentication Credentials Invalid

Hi,

We have been using SES for the past 4 years without any problem.

Last Saturday 19 March 2023, I created a new set of SMTP credentials to configure email sending method in Region Asia Pacific (Mumbai).

Encountered the below in Oracle Apex Mail Queue:

ORA-29279: SMTP permanent error: 535 Authentication Credentials Invalid

Upon searching and enquiring the reason, I found the policy attached - AmazonSesSendingAccess - has some Unrecognized actions .

Copy of the text from the page Edit AmazonSesSendingAccess is below:

Service

Pinpoint Email Actions Unrecognized actions IAM does not recognize one or more actions. The action name might include a typo or might be part of a previewed or custom service. SendRawEmail

Resources

Service

Where am I going wrong? Or Is it a problem at AWS SES, yet to be fixed?

Any help on this will be highly appreciated.

Thank you all. Raja
