Use SMTP with authentication to deliver messages from WordPress. Intercepts wp_mail function to allow you to define the server, port, connection security and credentials.
Designed initially as a replacement for the wp_mail function, this plugin uses the core WordPress mail functions and extends only the settings needed to allow connection to third-party mailing systems that require authentication and have sender and recipient restrictions.
Particularly good with Amazon SES where there are tight restrictions for sender lists and in sandbox mode only validated addresses may receive messages.
You can also simply use this to force sender and receivers for any messages from WordPress as well as set the default name in messages originating from your site.
Features:
<ul>
<li>Flexible configuration works with basically any mail service and protocol</li>
<li>Test function will allow you to diagnose specific errors in the email transmission</li>
<li>Able to handle Amazon Sandbox restrictions by overriding the recipient and sending only to an authorized address</li>
<li>Debug mode to capture transmission logs from phpmailer</li>
</ul>

MBC SMTP Flex

Extends wp_mail function to allow you to define the server, port, connection security and credentials.
