How can I set default setFrom in Zend_Mail - php

Question

How can I set the default setFrom field with title in Zend_Mail
If I send mail like this
public function sendActivationEmail($id) {
$mail = new Zend_Mail();
$mail ->addTo('emailId1#gmail.com',"Recepient Name")
->setFrom("emailId1#gmail.com","Site Name")
->setSubject("My Subject")
->setBodyText("Some body msg")
->setBodyHtml("Some body msg")
->send();
}
I get an email in nice format with From Field in mail as "Site Name"
But If I send mail without setFrom, I still get the mail, but the title is "emailId1#gmail.com". I dont want to use SetFrom() just to get "Site From". Is there a way I can set it so that "Site Name" gets picked up by default ?
I have followed this tutorial for setting up my email : http://www.zendcasts.com/introduction-to-zend_mail/2010/02/
Thank you,

If you want to set a default email address for the from attribute, you can use setDefaultFrom() static method like this:
For example, in your boostrap:
protected function _initFromMail(){
// You can get the mail from an init file
Zend_Mail::setDefaultFrom('emailId1#gmail.com', 'Site Name');
}
In your function, the from adress mail is automatically fiiled.
public function sendActivationEmail($id) {
$mail = new Zend_Mail();
$mail ->addTo('emailId1#gmail.com',"Recepient Name")
->setSubject("My Subject")
->setBodyText("Some body msg")
->setBodyHtml("Some body msg")
->send();
}

I would probably just create a subclass of Zend_Mail and use that. Something like the following:
class My_Mail extends Zend_Mail
{
public function __construct($charset = null)
{
parent::__construct($charset);
setFrom('emailId1#gmail.com, 'Site Name');
}
}
Then usage would be:
$mail = new My_Mail();
$mail ->addTo('emailId1#gmail.com','Recipient Name')
->setSubject('My Subject')
->setBodyText('Some body msg')
->setBodyHtml('Some body msg')
->send();
The usual requirements about how to autoload classes in the My_ pseudo-namespace would apply. For example, you could add:
autoloaderNamespaces[] = My_
to your application/config/application.ini
