Zend Mail - Where to instantiate it?

I'm using a Data Mapper / Gateway design pattern.

So I have a:

Mapper; Gateway; Domain Object (mainly with getters and setters); A controller; A view.

My question is: where should I instantiate the Zend Mail ? I believe the view is obviously out of question, and the gateway is, as well, not to be considered.

The controller should be kept clean, so:

Mapper our Domain Object ?

If our form will have some select box that will retrieve data from the database, then, perhaps the Mapper will be the most appropriate place to instantiate Zend Mail ?

Hmmmm? Well with Zend you can configure your Zend_Mail in your bootstrap or by using the application.ini file or some other config file. That's how I configure mine right now. For dev, I'll write the mails to a file and for testing I'll do mail over an actual mail server.

I instantiate my Zend_Mail instance in a class that I call Mail_Service. This mail service class will create a Zend_Mail instance internally when it needs to send a mail and will use an existing Zend_Mail instance if one has been created and more mails need to be sent.

It has methods that will send predefined mails for me. For example,

Mail_Service->sendWelcomeEmail( $userInfo ) 

OR

Mail_Service->sendActivationEmail( $userInfo )

Say for example my controller gets a request to create a new user, then the over all flow of my code will be like this

//in the controller
//process form from browser somehow

UserAccountService->createNewUser( $userInfo );



/////////////////
/// Within the user account service

public function createNewUser( $userInfo )
{
    $userMapper->createNewUser( $userInfo );
    $preferencesMapper->createDefaultPreferencesForUser( $userInfo );

    MailService->sendWelcomeEmail( $userInfo );
}

I don't know if this is the best way to do it, but this way my service have function names that are relevant to the service and capture a whole work flow instead of being atomic operations that just forward calls to other objects.

Hope this helps.

I always keep code that sends mail in my controllers.

Model - database/business logic

View - html / presentation layer

Controller - The code that does stuff.
