SES Mailer - SignatureDoesNotMatch

[stuartcusackie]

Laravel Version

12.32.5

PHP Version

8.3.15

Database Driver & Version

No response

Description

I opened this issue under the aws-sdk-php github but it may be a Laravel problem. I have never been able to successfully use the MAIL_MAILER=ses option. The SMTP option works fine when used in conjunction with AWS SES but new DigitalOcean accounts require us to use the SES driver as the normal SMTP ports are disabled on new DO servers.

Error logs:

Steps To Reproduce

Verify your SES domain and set up your IAM user using the default policy provided by the console:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "ses:SendRawEmail",
            "Resource": "*"
        }
    ]
}

Set up mail env vars like so:

MAIL_MAILER=ses
MAIL_FROM_ADDRESS=noreply@mywebsite.com
MAIL_FROM_NAME="My Website"

Set up AWS env vars like so (I am not using quotation marks):

AWS_ACCESS_KEY_ID=xxx
AWS_SECRET_ACCESS_KEY=yyy
AWS_DEFAULT_REGION=eu-west-1

Note that I am using the 'eu-west-1' region by default, perhaps there is a problem with regions. The mail is queueable and I see the failed jobs via my Horizon dashboard.

Hey there, thanks for reporting this issue.

We'll need more info and/or code to debug this further. Can you please create a repository with the command below, commit the code that reproduces the issue as one separate commit on the main/master branch and share the repository here?

Please make sure that you have the latest version of the Laravel installer in order to run this command. Please also make sure you have both Git & the GitHub CLI tool properly set up.

laravel new bug-report --github="--public"

Do not amend and create a separate commit with your custom changes. After you've posted the repository, we'll try to reproduce the issue.

Thanks!
