Support » Plugin: WP Offload SES Lite » Migrate to Signature Version 4 to continue using Amazon SES

  • Hi,

    I am using WP SES plugin in our website using AWS secret and key id.

    I am recently receiving below message from AWS.

    Amazon Simple Email Service (SES) had extended support for Signature Version 3 to February 28th, 2021. To continue to use Amazon SES, you must migrate to Signature Version 4 which offers enhanced security for authentication and authorization of Amazon SES customers.
    We have identified that, between 2021-03-22 and 2021-03-29, your AWS account 553361156523 used Signature Version 3 to call Amazon SES APIs in the us-east-1 Region.
    Your Signature Version 3 requests were identified to be originating from:
    - IAM Users: arn:aws:iam::------:user/sendynew
    - IPs:
    - User Agents: SimpleEmailService/php
    Your Signature Version 3 requests were identified to be using the following SES actions:
    - APIs: SendEmail
    Example Request ID using Signature Version 3: d2eeef38-18d9-49ee-bc04-516d42680246
    You can identify API requests that use Signature Version 3 by looking at the request headers. Requests that use the Signature Version 3 resemble the following example (note the "AWS3"):
    X-Amzn-Authorization: AWS3-HTTPS AWSAccessKeyId=AKIAIOSFODNN7EXAMPLE,Algorithm=HMACSHA256,Signature=lBP67vCvGl ...
    To move to Signature Version 4:
    - If you are self-signing your requests, refer to our documentation for Authenticating requests to the Amazon SES API [1] and creating a canonical request for Signature Version 4 [2].
    - If you are not self-signing your requests, simply update your SDK/CLI to the latest version.
    The Amazon SES team will update the request information weekly and will stop notifications once we identify that Signature Version 3 is no longer being used from your account.

    Also, in the SES setting, below message is appearing
    Sending emails through Amazon SES is currently OFF

    But mails are coming.
    Please suggest what should I do.
