Overriding Mage_Core_Model_Email_Template_Mailer class

Question

with this code (config.xml on my custom module):

<core>
<rewrite>
    <email_template>Company_Pluginname_Model_Email_Template</email_template>
    <email_template_mailer>Company_Pluginname_Model_Email_Template_Mailer</email_template_mailer>
</rewrite></core>

I override successfully the first model (Mage_Core_Model_Email_Template). But the second, Mage_Core_Model_Email_Template_Mailer not works... why? Thanks!

Here are some common overwrite issues that you can look out for:

• Wrong class definition. Your class should be something like class Company_Pluginname_Model_Email_Template_Mailer extends Mage_Core_Model_Email_Template_Mailer
• Wrong class file name. Your class file should be case sensitive app/code/[community|local]/Company/Pluginname/Model/Email/Template/Mailer.php
• Cache not cleared after config.xml changes
• Module dependencies not properly configured in the module definition XML files. In your case, in app/etc/modules/Company_Pluginname.xml you should have a <depends><Mage_Core /></depends> node.
• Overwritten resource is already overwritten by another module. You could grep the PHP code for the base class name Mage_Core_Model_Email_Template_Mailer, or config.xml files for email_template_mailer to check if this is the case
