I can confirm that it does work with CF7. What could be happening is that you are using an invalid FROM email address in your email template. Invalid for Mandrill, that is.
For security reasons, any email sent through wpMandrill should be sent from a valid “outbound domain”. If you are using something like “[your-name] <[your-email]>” as your From: field in your CF7 forms, any email sent from a domain not added to your Mandrill account will fail (asuming your-name and your-email as the CF7 variables that holds your visitor’s data).
You have two options to make it work:
1) The easiest way: To modify your CF7 email template by adding an “additional header” to your CF7 template: “Reply-To: [your-email]” and change the From: field to your own email address. You will probably want to add something like “[your-name] wrote:” in the body of the template so you could know the name of the sender.
2) Leave your template as is and use the mandrill_payload filter to make the Reply-To field to point to your visitor’s email address and then set the From: field to your regular, valid email address.
Something like this:
function mandrill_add_reply_to($message) {
$message['headers']['Reply-To'] = $message['from_email'];
$message['from_name'] = 'Your Name';
$message['from_email']= '[email protected]';
return $message;
}
add_filter('mandrill_payload','mandrill_add_reply_to');
