The administrative interface is at admin/config/system/mailsystem. A screenshot is available.

Developers API

A module example with a MailSystemInterface implementation called ExampleMailSystem should add the following in its example.install file:

/**
 * Implements hook_enable().
 */
function example_enable() {
  mailsystem_set(array('example' => 'ExampleMailSystem'));
}
/**
 * Implements hook_disable().
 */
function example_disable() {
  mailsystem_clear(array('example' => 'ExampleMailSystem'));
}

The above settings allow mail sent by example to use ExampleMailSystem. To make ExampleMailSystem the site-wide default for sending mail:

mailsystem_set(array(mailsystem_default_id() => 'ExampleMailSystem'));

To restore the default mail system:

mailsystem_set(array(mailsystem_default_id() => mailsystem_default_value()));

Or simply:

mailsystem_set(mailsystem_defaults());

If module example relies on dependency foo and its FooMailSystem class, then the example.install code should like like this:

/**
 * Implements hook_enable().
 */
function example_enable() {
  mailsystem_set(array('example' => 'FooMailSystem'));
}
/**
 * Implements hook_disable().
 */
function example_disable() {
  mailsystem_clear(array('example' => ''));
}

If module example only wants to use FooMailSystem when sending emails with a key of examail, then the example.install code should look like this:

/**
 * Implements hook_enable().
 */
function example_enable() {
  mailsystem_set(array('example_examail' => 'FooMailSystem'));
}
/**
 * Implements hook_disable().
 */
function example_disable() {
  mailsystem_clear(array('example_examail' => ''));
}

(New in 2.x branch)

To change the site-wide defaults to use the FooMailSystem for formatting messages and the BarMailSystem for sending them:

mailsystem_set(
  array(
    mailsystem_default_id() => array(
      'format' => 'FooMailSystem',
      'mail' => 'BarMailSystem',
    ),
  )
);

To change the site-wide defaults to use the FooMailSystem for sending messages, while continuing to use the current system for formatting them:

mailsystem_set(
  array(
    mailsystem_default_id() => array(
      'mail' => 'FooMailsystem',
    ),
  )
);
