Subscribe by email via Mandrill

Hi,

I would like to use the subscribe by email plugin but need it to send via Madrill servers.

It is at the moment sending via my own server despite the mandrill plugins which is supped to override the default WP sending.

I assume this is due the plugins own sending function.

I wonder if you are able to help me and offer some pointers for where to add to or modify your plugin by replacing the mail sending code with the mandrill sending code/function.

I have some instruction from Mandrill but am not sure where to start looking.

Thanks.

Stef
