## Description

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:

 * Flexible configuration works with basically any mail service and protocol
 * Test function will allow you to diagnose specific errors in the email transmission
 * Able to handle Amazon Sandbox restrictions by overriding the recipient and sending
   only to an authorized address
 * Debug mode to capture transmission logs from phpmailer

 5. Send a test message, confirm delivery and Activate to allow the plugin to extend

## FAQ

  How to I fix a connection failure problem?

If the plugin is unable to connect to your server, ensure the following:

 * Ensure your server’s outbound ports allow traffic over your SMTP port
 * Try to ping the SMTP host directly from your server if you have SSH available
 * Consider a CNAME wrapper to the host if your hosting company is blocking that
   domain
 * Check whitelist/blacklist options with SMTP server host and whitelist your server
   IP if possible
 * Ensure OpenSSL is available on the server (OPENSSL_VERSION_TEXT) if you are using
   ssl or tls for connection security

  How to I configure this for Amazon SES?

To configure the plugin for Amazon Simple Email Service:

 * Setup your domain with Amazon SES and ensure the DNS settings are entered to 
   validate the domain (we recommend using Route 53 to simplify the process)
 * If you are new to Amazon SES, you need to force both the sender and recipient
   while in sandbox mode to a verified address
 * In order to get out of sandbox mode, you need to request a quota limit change,
   with the request to allow to valid recipients. Please read this article for more
   information: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/request-production-
   access.html
 * For TLS connections, use port 587 and for SSL use port 465
 * When you are out of the sandbox mode, you can deselect the force recipient option
   and test to an arbitrary email address
