README

Provides Mandrill integration for Symfony Mailer.

Configuration example:

# SMTP
MAILER_DSN=mandrill+smtp://USERNAME:PASSWORD@default

# HTTP
MAILER_DSN=mandrill+https://KEY@default

# API
MAILER_DSN=mandrill+api://KEY@default

where:

• KEY is your Mailchimp API key

Custom Return Path Domains

When using the mandrill+api transport, you can set a custom domain for the return path of the message (which Mandrill uses to handle bounces) by adding the X-MC-ReturnPathDomain header to the email:

$email->getHeaders()->addTextHeader('X-MC-ReturnPathDomain', 'example.com');

Note

Support for the X-MC-ReturnPathDomain header was introduced in Symfony 8.2.
