You can’t use {{from_email}} @ xyz.com. It should only be {{from_email}} as the whole thing gets subbed in.
It appears you can only use one template (the one you selected in wordpress) and cannot change it depending on where the email originates like Mandrill using code (what rbarron said)
I hope theres an update soon to allow that.
Same problem with 2.2.1 and Reply-To being stripped out.
I think all headers are stripped out as I can’t get BCC to work and wpMandrill was working flawlessly with the same headers.

I second this. Any luck with customization similar to the mandrill payload where we can select the templates programmatically depending on which email is being sent? (ex. New account would have a template, password reset can use another template, etc…)
Thanks.
