Edit the Omeka S local.config.php file as follows.

<?php
return [
    'logger' => [
        // Log settings (as needed)
    ],
    'mail' => [
        'transport' => [
            'type' => 'smtp', // Use SMTP
            'options' => [
                'name' => 'ses-smtp-user',         // Any name
                'host' => 'email-smtp.us-east-1.amazonaws.com',  // SES SMTP server endpoint
                'port' => 587,                                 // Port supported by SES (e.g., 587)
                'connection_class'  => 'plain',                // Authentication type
                'connection_config' => [
                    'username' => 'your-ses-smtp-username',   // SES SMTP username
                    'password' => 'your-ses-smtp-password',   // SES SMTP password
                    'ssl'      => 'tls',                      // SSL type ('tls' recommended)
		    'use_complete_quit' => true,
                ],
            ],
        ],
    ],
    // Other settings...
];
  • For host, specify the Amazon SES SMTP server endpoint corresponding to the AWS region you are using. The example uses the us-east-1 region endpoint, but change it as needed.
  • For username and password, use the SMTP credentials generated in Amazon SES.
